    Materials & Construction

    TPU Reinforced Hose uses thermoplastic polyurethane as the primary polymer matrix. TPU is available in different polyester-based and polyether-based formulations, allowing the material to be selected according to requirements such as hydrolysis resistance, oil resistance, abrasion resistance, flexibility, and environmental exposure.

    A reinforcing layer is integrated within the hose wall to provide additional tensile strength and control dimensional expansion under pressure. Depending on the intended service conditions, reinforcement can be designed using high-strength textile or other suitable structures.

    The TPU inner layer provides the primary contact surface for the conveyed medium. Its smooth bore reduces turbulence and helps facilitate the movement of fluids, powders, or granular materials. The outer TPU layer protects the reinforcement and contributes to resistance against abrasion, impact, and repeated bending.

    Material hardness and wall construction can be adjusted to achieve different combinations of flexibility and mechanical strength. For dynamic applications, the construction can prioritize flex life, while pressure-transfer applications may require a higher reinforcement density.

    Applications

    Reinforced flexible hose is widely used in industrial environments where conventional PVC hoses may experience excessive abrasion, flex fatigue, or mechanical wear. Typical applications include pneumatic conveying, industrial air lines, material handling, agricultural equipment, machinery connections, slurry transfer, and selected oil or fluid-transfer systems.

    Its high abrasion resistance makes it particularly valuable for conveying dry powders, granules, pellets, dust, and other particulate materials that can progressively wear the internal wall of ordinary flexible tubing. In pneumatic conveying systems, the hose can be used for connections between fixed pipes and moving machinery where flexibility is required.

    TPU’s flexibility and resistance to repeated bending also make it suitable for mobile equipment and automated machinery. Depending on the selected TPU formulation, it can provide improved resistance to oils, moisture, hydrolysis, and low-temperature exposure.

    For fuels, concentrated chemicals, high-temperature media, or highly specialized fluids, material compatibility should be confirmed with the specific TPU grade before use.

    TPU Reinforced Hose

    Manufacturing & Quality Control

    TPU reinforced hose is produced using controlled thermoplastic extrusion and reinforcement integration technology. TPU pellets are first dried and conditioned according to the material manufacturer’s processing requirements, since excessive moisture during processing can affect surface quality, mechanical properties, and dimensional stability.

    The TPU material is then plasticized and extruded under controlled temperature and pressure conditions. The reinforcement layer is introduced at a controlled position within the hose wall, followed by the formation of the outer TPU layer. Precise control of extrusion speed, melt temperature, reinforcement tension, and cooling conditions is essential for maintaining concentricity and consistent wall construction.

    During production, dimensional parameters such as inner diameter, outer diameter, wall thickness, and reinforcement position are monitored. Particular attention is given to the bonding and encapsulation of the reinforcement because incomplete coverage can create weak points during pressure cycling or repeated bending.

    Finished hoses undergo visual and dimensional inspection. Depending on the application, additional testing can include tensile strength, elongation, hardness, pressure resistance, leakage, flex-fatigue, abrasion, and low-temperature performance evaluation.

    For OEM projects, inspection criteria can be established according to customer drawings, technical specifications, or agreed quality standards. Production batches can also be identified and documented to support consistent repeat orders.

    TPU Reinforced Hose

    Customization / OEM & ODM

    TPU reinforced hose can be engineered around the mechanical and environmental requirements of the end application. Yozonetech supports customized development for customers who require specific dimensions, pressure levels, flexibility, or material performance.

    The process begins by reviewing the conveyed medium, operating pressure, temperature, bending frequency, required service life, hose dimensions, and connection method. Based on these conditions, we can recommend an appropriate TPU grade, hardness, reinforcement configuration, and wall structure.

    Customization options include:

    • TPU formulation and hardness
    • Polyester-based or polyether-based TPU
    • Inner and outer diameter
    • Wall thickness
    • Reinforcement material and density
    • Transparent or colored construction
    • Hose length and coil configuration
    • Surface printing and identification
    • Fittings, cuffs, and end connections
    • Customized packaging and private labeling

    Customers can provide drawings, existing samples, equipment interfaces, or performance requirements. Prototype samples can be produced for dimensional and application testing before mass production. This allows the final hose construction to be validated against the customer’s actual equipment rather than relying solely on theoretical specifications.

    FAQ

    1. What makes TPU reinforced hose different from PVC reinforced hose?

    TPU generally offers significantly higher abrasion resistance and better resistance to repeated flexing than standard PVC. It is particularly advantageous for abrasive material conveying and dynamic applications where mechanical wear is a major concern.

    2. Is TPU suitable for conveying abrasive powders and granules?

    Yes. TPU is widely used for abrasive particulate conveying because of its strong resistance to wear. The appropriate wall thickness and hardness should be selected according to particle characteristics, conveying velocity, and operating frequency.

    3. Should I choose polyester TPU or polyether TPU?

    The choice depends on the environment. Polyether TPU generally provides better hydrolysis resistance and can be advantageous in humid or water-exposed applications, while polyester TPU often provides strong mechanical and abrasion performance and good resistance to many oils and fuels. The actual medium and environment should be evaluated before selection.

    4. Can the hose be manufactured with a specific pressure rating?

    Yes. Pressure performance can be influenced by hose diameter, wall thickness, TPU hardness, and reinforcement structure. We can design the construction around a specified working pressure and required safety margin.

    5. Can you develop a TPU hose based on an existing product?

    Yes. OEM/ODM development can be based on a sample, technical drawing, dimensional specification, or application requirement. Our production team can analyze the construction and develop a corresponding specification for sample approval and subsequent mass production.

    Materials & Construction

    The hose uses flexible PVC as the primary body material, with a continuous spiral steel wire integrated into the wall during manufacturing. The steel wire functions as the structural backbone of the hose rather than simply serving as an external reinforcement. This is particularly important in suction applications, where atmospheric pressure acts against the hose wall when the internal pressure falls below ambient pressure.

    The spiral configuration allows the hose to bend while maintaining mechanical support along its length. When routed around vacuum cleaners, extraction units, or industrial equipment, the hose can change direction without requiring multiple rigid elbows.

    The PVC wall provides the working surface for the conveyed material and contributes flexibility, abrasion resistance, and environmental protection. Depending on the intended application, the formulation and wall thickness can be adjusted to balance flexibility, vacuum resistance, wear performance, and weight.

    For applications involving abrasive particles, the internal construction can be selected according to particle size, concentration, conveying velocity, and operating frequency.

    Applications

    PVC Steel Wire Vacuum Cleaner Hose is primarily used in equipment where negative pressure is generated to draw air, dust, debris, or lightweight particles through a flexible hose. Typical applications include industrial vacuum cleaners, commercial cleaning machines, workshop dust extractors, central vacuum systems, woodworking dust collection, and general-purpose extraction equipment.

    In woodworking and fabrication environments, the hose can connect dust-producing machinery to collection systems, allowing chips and airborne particles to be removed from the working area. For industrial cleaning equipment, its flexible construction allows operators to move the suction hose while the machine remains stationary.

    The transparent version is particularly useful where visual inspection of the conveyed material is important. Operators can observe airflow and material movement, identify accumulation, and detect potential blockages without immediately disconnecting the hose.

    For heavy abrasive particles, elevated temperatures, conductive dust, or chemically aggressive media, the hose construction should be evaluated against the actual operating conditions before selection.

    PVC Steel Wire Vacuum Cleaner Hose

    Manufacturing & Quality Control

    The manufacturing process is designed around the dimensional relationship between the PVC wall and the embedded spiral steel wire. PVC material is prepared according to the required flexibility, hardness, transparency, and environmental performance. The steel wire is formed into a controlled spiral before being integrated with the extruded PVC structure.

    During production, the wire pitch, wire positioning, PVC wall thickness, and extrusion conditions are continuously controlled. Consistent wire geometry is particularly important because variations in spiral pitch or embedding depth can influence flexibility, bending behavior, and resistance to vacuum-induced deformation.

    After forming, the hose passes through controlled cooling to stabilize its dimensions. Finished sections are then inspected for inner diameter, outer diameter, wall thickness, surface quality, wire continuity, and overall dimensional consistency. Visual inspection is used to identify defects such as uneven PVC coverage, exposed reinforcement, surface damage, or irregular spiral formation.

    Where required, production can include vacuum-resistance evaluation, pressure testing, flexibility assessment, dimensional verification, and batch inspection. Testing conditions can be established according to the customer’s equipment specifications rather than relying on a single universal vacuum rating.

    Before shipment, hoses are cut or coiled according to the agreed configuration and protected against deformation during transportation. Production records and inspection information can be provided for orders requiring traceability or controlled quality documentation.

    PVC Steel Wire Vacuum Cleaner Hose

    Customization / OEM & ODM

    Vacuum hose performance is strongly influenced by the geometry of the hose and the vacuum equipment to which it is connected. Yozonetech therefore supports application-based OEM and ODM development rather than limiting customization to diameter and length.

    The development process begins with the customer’s vacuum level, airflow, hose diameter, conveying material, operating temperature, bending requirements, and connection method. Our technical team can then determine an appropriate PVC wall structure and spiral steel-wire configuration.

    Available customization options include:

    • Inner diameter and outer diameter
    • PVC wall thickness
    • Steel-wire diameter and spiral pitch
    • Hardness and flexibility
    • Transparent, translucent, or colored PVC
    • Hose length and coil dimensions
    • Connector, cuff, flange, or fitting configuration
    • Surface printing and identification

    2. Is this hose suitable for industrial dust extraction?

    Yes. It can be used for many industrial dust and debris extraction systems, including woodworking, workshop cleaning, machinery dust collection, and industrial vacuum equipment. The exact construction should be selected according to the type and abrasiveness of the material being conveyed.

    3. Can the hose be connected directly to a vacuum cleaner?

    Yes. The hose can be manufactured or supplied with suitable cuffs, clamps, connectors, or other end configurations. The connection dimensions should be confirmed according to the vacuum cleaner or extraction equipment.

    4. Can you make a more flexible or more rigid version?

    Yes. Flexibility can be adjusted through PVC formulation, wall thickness, steel-wire diameter, and spiral geometry. The final construction can be optimized according to bending radius and vacuum requirements.

    5. Can you manufacture the hose according to an existing sample?

    Yes. OEM development can be based on a physical sample, drawing, dimensional specification, or existing hose. We can evaluate the construction and develop a corresponding production specification for approval before bulk manufacturing.

    Materials & Construction

    The reinforced flexible hose consists of a flexible PVC matrix surrounding a continuous spiral steel wire. Unlike textile-reinforced pressure hose, where reinforcement is primarily intended to withstand internal pressure, the steel helix in this construction provides radial support along the entire length of the hose. This makes the design particularly effective for suction and vacuum applications.

    The steel wire is formed into a controlled spiral and integrated into the PVC wall during extrusion. Its pitch and diameter influence several performance characteristics, including bending radius, crush resistance, vacuum stability, weight, and overall flexibility.

    The inner PVC surface provides the direct contact path for the conveyed material. A smooth bore helps maintain consistent flow and reduces locations where particles can accumulate. The outer PVC layer protects the embedded steel wire against normal environmental exposure and mechanical handling.

    PVC formulations can be modified according to the intended service. Softer compounds can provide easier bending, while a more rigid formulation and stronger wire structure can improve resistance to deformation. For abrasive media, wall thickness and material formulation can be adjusted to extend service life.

    Applications

    PVC Spiral Steel Wire Hose is widely used in suction, discharge, and material-transfer systems where flexibility and structural stability are required simultaneously. Typical applications include agricultural irrigation, water suction, pump connections, industrial vacuum systems, slurry transfer, liquid handling, and pneumatic or mechanical transport of selected particulate materials.

    In agricultural equipment, the hose can be used between pumps, tanks, irrigation systems, and water sources. Its flexible construction allows the suction line to follow equipment movement and uneven installation paths.

    Industrial applications include transferring water, wastewater, light chemicals, slurry, powders, pellets, and other compatible materials. Transparent versions are especially useful when operators need to observe the flow condition or identify blockages without dismantling the system.

    The steel-wire structure also makes the hose suitable for applications where a flexible connection must withstand external bending and negative pressure. For highly abrasive solids, concentrated chemicals, elevated temperatures, or demanding continuous vacuum service, the hose construction should be selected according to the actual operating parameters.

    PVC Spiral Steel Wire Hose

    Manufacturing & Quality Control

    Manufacturing PVC spiral steel wire hose requires accurate coordination between PVC extrusion and steel-wire forming. The PVC compound is prepared according to the required flexibility, hardness, transparency, and environmental performance. Steel wire is formed into a controlled helical geometry before being integrated into the hose wall.

    During production, extrusion temperature, material flow, line speed, wire tension, spiral pitch, and embedding position are controlled continuously. Correct wire placement is critical: insufficient PVC coverage can expose the reinforcement, while excessive displacement can create variations in wall thickness and affect bending characteristics.

    After the hose is formed, controlled cooling stabilizes the PVC profile and helps maintain dimensional accuracy. Finished hose is inspected for inner diameter, outer diameter, wall thickness, spiral uniformity, surface condition, and overall appearance.

    For applications involving suction or pressure, additional performance checks can be conducted according to the agreed specification. These may include vacuum-resistance testing, pressure testing, leakage inspection, bending evaluation, and dimensional recovery after deformation.

    Particular attention is paid to the transition between the steel-wire-reinforced body and the hose ends, where cutting and connection can influence installation quality. Finished products are coiled and packaged in a way that minimizes permanent deformation during transportation and storage.

    For OEM production, inspection criteria can be established in advance, including dimensional tolerances, wire specifications, vacuum requirements, pressure requirements, and appearance standards.

    PVC Spiral Steel Wire Hose

    Customization / OEM & ODM

    PVC spiral steel wire hose is highly dependent on the relationship between hose diameter, wall thickness, steel-wire geometry, and operating conditions. Yozonetech provides OEM and ODM development for applications requiring a specific balance of flexibility, vacuum resistance, pressure capability, and wear performance.

    The process starts with the customer’s medium, working pressure, vacuum level, temperature, flow characteristics, hose diameter, bending radius, and connection method. These parameters are used to determine the appropriate PVC formulation and steel-wire structure.

    Customization options include:

    • Inner and outer diameter
    • PVC hardness and formulation
    • Wall thickness
    • Steel-wire diameter
    • Spiral pitch
    • Wire material and surface treatment
    • Transparency and color
    • Hose length and coil configuration
    • Smooth or customized surface
    • Clamps, cuffs, flanges, and other connections
    • Surface printing and identification

    FAQ

    1. What is the main purpose of the steel wire inside the hose?

    The spiral steel wire acts as a continuous structural support. It helps prevent the PVC wall from collapsing when the hose is subjected to negative pressure and also improves resistance to external deformation.

    2. Is PVC spiral steel wire hose suitable for suction applications?

    Yes. This is one of its primary applications. The steel-wire helix helps maintain the internal passage under vacuum. However, the appropriate wire diameter, pitch, and wall thickness must be selected according to the required vacuum level.

    3. Can this hose be used for both suction and discharge?

    Yes, depending on its construction. The required working pressure and vacuum rating should be considered together when selecting the hose. A hose optimized for suction should not automatically be assumed to have a high positive-pressure rating.

    4. What is the advantage of a transparent version?

    A transparent or translucent hose allows operators to observe the conveyed material. This can help identify flow interruptions, air pockets, blockages, or contamination without opening the system.

    5. Can the steel wire and spiral pitch be customized?

    Yes. Wire diameter and spiral pitch can be adjusted according to the required flexibility, crush resistance, vacuum performance, and mechanical strength. Custom construction is particularly useful for OEM equipment and specialized suction systems.

    Materials & Construction

    The reinforced flexible hose is manufactured primarily from flexible PVC, selected for its combination of flexibility, abrasion resistance, weatherability, and economical processing. A reinforced layer is incorporated into the hose wall to improve dimensional stability and pressure performance during operation.

    The inner PVC layer forms a smooth flow channel, helping fluids pass through the hose with relatively low flow resistance. The reinforcement layer provides additional mechanical strength and helps limit radial expansion when internal pressure increases. An outer PVC layer protects the reinforcement from abrasion, moisture, and normal handling conditions.

    Different reinforcement densities can be selected according to the intended working pressure and flexibility requirements. For applications requiring easier handling, a lighter reinforcement structure can be used, while higher-pressure applications can utilize a denser reinforcement layer. This construction allows the same basic hose design to be adapted to different industrial and commercial requirements.

    Applications

    PVC Reinforced Hose is widely used where flexible pressure transfer is required without the weight and rigidity of conventional rigid piping. It is commonly used for water delivery, agricultural irrigation, air transfer, equipment connections, machinery, cleaning systems, and general industrial fluid handling.

    In agricultural applications, the hose can be used for irrigation and water distribution where frequent movement and installation flexibility are important. In workshops and factories, it can connect pumps, equipment, tanks, and processing systems. Its flexible construction is also useful for temporary or semi-permanent connections where rigid pipes would be inconvenient.

    The hose can handle many commonly used fluids, but compatibility should be confirmed before use with oils, aggressive chemicals, high-temperature media, or other specialized fluids. For demanding applications, Yozonetech can recommend an appropriate PVC formulation and reinforcement structure based on the actual working conditions.

    PVC Reinforced Hose

    Manufacturing & Quality Control

    Yozonetech manufactures PVC reinforced hose through controlled extrusion and reinforcement processes designed to maintain consistent dimensions and bonding between the hose layers. PVC raw materials are prepared according to the required formulation before being processed through precision extrusion equipment.

    During production, the inner PVC layer is formed first, followed by the reinforcement layer and outer PVC covering. Process parameters such as extrusion temperature, material feeding, line speed, and cooling conditions are controlled to maintain a stable hose structure. The reinforcement is positioned evenly around the hose to reduce variations in wall thickness and pressure performance.

    After extrusion, the hose is cooled, measured, cut to the specified length, and visually inspected. Quality control focuses on key characteristics including inner and outer diameter, wall thickness, surface appearance, flexibility, reinforcement position, and dimensional consistency. Pressure testing can also be performed according to customer requirements.

    Before shipment, finished hoses are checked against production specifications and packaging requirements. Customized labels, markings, rolls, coils, and packaging configurations are available for different markets and distribution channels.

    Materials & Construction

    The reinforced flexible hose is manufactured from polyurethane selected for its combination of wear resistance, flexibility, tensile strength, and resistance to repeated mechanical deformation. For oil-exposed environments, the PU formulation can be selected according to the type of oil, lubricant, concentration, temperature, and exposure duration.

    The anti-static function is achieved through an electrically dissipative or conductive material system incorporated into the hose rather than relying solely on an external coating. This allows static charge generated during pneumatic conveying or material movement to be controlled through a suitable grounding path.

    For demanding applications, polyester-based or polyether-based PU can be considered according to the environment. Polyether PU is often advantageous where moisture and hydrolysis resistance are important, while polyester PU can provide strong mechanical and abrasion performance in many industrial applications.

    The hose can be manufactured as a single-wall flexible tube or with additional reinforcement where pressure stability is required. Wall thickness, hardness, conductivity, and reinforcement can be adjusted to meet the requirements of the complete conveying system.

    Applications

    Oil-resistant and anti-static PU hose is commonly used in pneumatic conveying, industrial vacuum systems, powder transfer, plastics processing, woodworking dust collection, automated machinery, and equipment requiring flexible air or material connections.

    It is particularly useful in systems conveying dry powders, plastic pellets, granules, dust, and other particulate materials where friction can generate static electricity. The dissipative construction helps reduce charge accumulation when the hose is correctly incorporated into a grounded system.

    The oil-resistant formulation also makes the hose suitable for machinery and workshop environments where contact with lubricating oils, cutting fluids, or oil mist may occur. Its flexibility allows connections between moving components, robotic equipment, extraction units, and fixed pipelines.

    Typical applications include plastic pellet conveying, CNC dust extraction, pneumatic material transfer, industrial vacuum cleaners, woodworking equipment, air-operated machinery, and selected oil-containing pneumatic environments.

    For combustible dust or potentially explosive atmospheres, hose electrical properties must be evaluated as part of the complete system. An anti-static hose alone does not constitute a complete explosion-protection solution.

    Oil-Resistant & Anti-Static PU Hose

    Manufacturing & Quality Control

    Production begins with the selection and preparation of a PU compound designed to provide the required combination of oil resistance, abrasion performance, flexibility, and electrical behavior. For specialized applications, the formulation is developed around the customer’s conveying medium and operating environment.

    The PU material is processed through precision extrusion equipment under controlled thermal and mechanical conditions. Melt temperature, extrusion pressure, die geometry, and line speed are monitored to maintain consistent wall dimensions. For anti-static products, electrical performance depends on maintaining a uniform distribution of the conductive or dissipative component throughout the specified material structure.

    During continuous production, inner diameter, outer diameter, wall thickness, surface appearance, and dimensional stability are monitored. Special attention is given to electrical resistance because excessive variation can affect static-dissipation performance. Samples from production batches can be tested using agreed electrical-resistance methods.

    Depending on the application, additional quality checks may include hardness, tensile strength, elongation, pressure resistance, leakage, abrasion resistance, oil immersion, heat aging, and repeated-flex testing.

    For OEM orders, acceptance criteria can be defined before production, including dimensional tolerances, electrical resistance range, material grade, packaging, and identification requirements. This allows subsequent production batches to be evaluated against the same technical baseline.

    Oil-Resistant & Anti-Static PU Hose

    Customization / OEM & ODM

    Anti-static PU hose should be specified according to the entire conveying system rather than simply selecting a nominal hose diameter. Yozonetech supports OEM and ODM development for customers with specific requirements for electrical properties, oil resistance, pressure, flexibility, and abrasion performance.

    The process starts with collecting the conveyed material, oil or chemical exposure, operating pressure, temperature, airflow, hose dimensions, bending frequency, and grounding requirements. The appropriate PU formulation and electrical construction can then be selected.

    Customization options include:

    • Polyester or polyether PU
    • Oil-resistant formulation
    • Conductive or dissipative grade
    • Target electrical resistance
    • Inner and outer diameter
    • Wall thickness
    • Hardness
    • Reinforcement structure

    • Hose length and coil configuration
    • Fittings and end connections
    • Surface printing and private labeling

    For new projects, customers can provide an existing hose sample, technical drawing, equipment interface, or electrical-performance requirement. Prototype samples can be produced for dimensional, mechanical, oil-resistance, and electrical evaluation before mass production.

    FAQ

    1. Why does a pneumatic conveying system need an anti-static hose?

    High-speed movement of dry powders, granules, or dust can generate electrostatic charge through friction. An electrically dissipative hose can help prevent excessive charge accumulation when connected to an appropriate grounding system.

    2. Is anti-static PU hose suitable for oil exposure?

    Yes, selected PU formulations provide good resistance to oils and lubricants. However, resistance varies according to the specific oil type, concentration, temperature, and exposure time, so the actual medium should be confirmed before selection.

    3. Is an anti-static hose automatically suitable for explosive environments?

    No. Anti-static performance is only one component of a complete safety system. For combustible dust or explosive atmospheres, electrical resistance, grounding, equipment design, and applicable safety requirements must all be evaluated.

    4. What is the difference between conductive and dissipative PU?

    The distinction is primarily related to electrical resistance and the rate at which charge can be transported away. The appropriate resistance range should be selected according to the conveying system, grounding design, and applicable technical requirements.

    5. Can you manufacture PU hose according to a required electrical resistance?

    Yes. For OEM projects, the electrical resistance range can be incorporated into the product specification. Customers should provide the intended test method and target resistance where applicable so that production and inspection criteria can be aligned.

    Materials & Construction

    Flexible industrial hose can be manufactured from several thermoplastic materials, allowing the construction to be matched to the application rather than relying on a universal polymer. Common options include polyurethane (PU/TPU), polyamide (PA), polyethylene (PE), PVC, and other engineering thermoplastics.

    For pneumatic automation, polyurethane is often selected when flexibility, repeated bending, and abrasion resistance are important. Polyamide can be considered where higher pressure capability, dimensional stability, or elevated-temperature performance is required. PE can provide a lightweight and economical solution for selected low-pressure applications, while PVC may be suitable for general-purpose fluid transfer.

    The hose may be produced with a smooth single-layer wall for standard applications or modified with reinforcement and special formulations where higher pressure, chemical resistance, or environmental durability is required.

    Accurate extrusion control is essential because pneumatic fittings depend heavily on the hose’s outside diameter, roundness, and surface condition. Consistent dimensions help reduce leakage and improve connection reliability during installation.

    Applications

    Fluid and pneumatic hoses are widely used in factory automation, compressed-air systems, pneumatic control circuits, instrumentation, machinery, fluid distribution, and equipment interconnections. Typical pneumatic applications include connections between air preparation units, solenoid valves, cylinders, actuators, pressure regulators, manifolds, and control panels.

    In automated machinery, flexible tubing provides a practical method of routing compressed air around moving assemblies without requiring rigid pipework. Small-diameter hoses are particularly useful in compact machine layouts where installation space is limited.

    For fluid applications, suitable material grades can be selected for water, cooling circuits, lubrication systems, and other compatible low-to-medium pressure media. The appropriate hose should always be selected according to fluid chemistry, temperature, pressure, and exposure duration.

    For robotic and dynamic applications, the hose construction can be optimized for repeated bending and movement. Where the hose is installed inside cable carriers or subjected to continuous flexing, a material and wall design specifically intended for dynamic service should be considered.

    Fluid Hose & Pneumatic Hose

    Manufacturing & Quality Control

    Manufacturing begins with polymer selection based on the required pressure, flexibility, temperature range, media compatibility, and connection system. Thermoplastic raw materials are prepared and processed through precision extrusion equipment to produce a continuous tube with controlled dimensions.

    During extrusion, melt temperature, die geometry, extrusion speed, cooling rate, and material flow are monitored to maintain a stable profile. For pneumatic tubing, particular attention is given to outside diameter and roundness because these dimensions directly influence the sealing performance of push-in and compression fittings.

    The production line continuously monitors key dimensional parameters. Finished tubing is inspected for inner diameter, outer diameter, wall thickness, surface quality, and length accuracy. Visual inspection is used to identify scratches, bubbles, surface contamination, deformation, or other defects that could affect connection integrity.

    Depending on the product specification, additional tests may include working-pressure verification, burst-pressure testing, leakage testing, tensile and elongation testing, hardness measurement, heat aging, low-temperature flexibility, and chemical compatibility evaluation.

    For pneumatic tubing supplied in long continuous coils, controlled winding and packaging are also important. Proper coiling helps prevent excessive deformation and ensures the hose can be easily unwound during installation. OEM orders can be manufactured according to approved drawings, dimensional tolerances, testing requirements, and packaging specifications.

    FAQ

    1. Which material is best for pneumatic hose?

    There is no single material suitable for every pneumatic system. PU is often preferred for flexibility and dynamic applications, while PA can be advantageous for higher pressure and dimensional stability. The correct choice depends on pressure, temperature, fittings, and movement requirements.

    2. Can the same hose be used for both air and water?

    Some materials are compatible with both compressed air and water, but the operating pressure, temperature, and chemical environment must be checked separately. A hose suitable for pneumatic service is not automatically suitable for every fluid.

    3. Why is outside diameter important for pneumatic tubing?

    Many pneumatic fittings seal against the hose’s outside surface. Variations in diameter, ovality, or surface quality can affect insertion force and sealing performance, making extrusion accuracy particularly important for pneumatic tubing.

    4. Can you supply tubing in custom colors?

    Yes. Color can be customized for equipment identification, circuit differentiation, branding, or visual requirements, subject to material and production-volume considerations.

    Materials & Construction

    The duct is manufactured from fiberglass fabric coated with silicone rubber and assembled as a double-layer flexible structure. Fiberglass serves as the primary reinforcement substrate because of its ability to retain mechanical integrity at elevated temperatures. The silicone coating protects the fabric from moisture, surface contamination, and environmental exposure while providing flexibility to the finished duct.

    The two-layer configuration increases the material thickness and creates a more robust barrier between the hot airflow and the surrounding environment. It also improves resistance to handling damage during installation and repeated repositioning.

    Depending on the required diameter and operating conditions, the fabric layers can be configured with different weights, weave structures, coating thicknesses, and reinforcement arrangements. Additional structural elements may be incorporated when the duct needs improved shape retention or resistance to external compression.

    The resulting construction is substantially different from thermoplastic hoses: it is primarily engineered as a high-temperature flexible ducting system, where thermal performance, airflow management, installation flexibility, and fabric durability are more important than conventional fluid-pressure performance.

    Applications

    Flexible industrial hose is designed primarily for the movement of hot air, exhaust gases, fumes, and thermally loaded air streams. It is commonly used around industrial heaters, ovens, furnaces, dryers, engines, generators, welding equipment, exhaust systems, and specialized ventilation machinery.

    The duct is particularly useful when the connection between two components requires flexibility and cannot be accommodated efficiently with rigid metal ducting. Its fabric construction allows it to follow equipment movement and complex routing paths while reducing the number of rigid bends and intermediate connections.

    Typical applications include hot-air extraction, engine compartment ventilation, welding fume extraction, industrial oven exhaust, heating equipment, thermal processing machinery, and mobile ventilation systems.

    Before selection, the actual gas composition, temperature, airflow velocity, installation length, bending radius, and exposure duration should be considered. Applications involving corrosive chemicals, direct flame, molten materials, or highly abrasive particles may require a specially formulated construction.

    Double-Layer Silicone Fiberglass Cloth Duct

    Manufacturing & Quality Control

    Production of the double-layer silicone fiberglass duct involves controlled preparation of the fiberglass fabric, silicone coating, layer forming, cutting, joining, reinforcement, and final dimensional inspection. Fiberglass cloth is selected according to the required thermal and mechanical performance before the silicone coating process.

    During coating, silicone is applied uniformly to the fiberglass substrate to achieve consistent coverage and stable adhesion. Coating thickness is controlled according to the intended application because it affects flexibility, surface protection, and overall durability. After coating, the fabric is processed into the required duct configuration.

    The double-layer structure is assembled with controlled overlap and joining methods to maintain consistent wall construction around the circumference. For reinforced or shaped ducts, the structural components are positioned according to the specified pitch and geometry. Particular attention is given to the transition between the duct body and end connections, as these areas experience concentrated mechanical loads during installation.

    Finished ducts undergo dimensional inspection covering inner diameter, length, wall appearance, connection dimensions, and construction uniformity. Visual inspection checks for coating defects, exposed fabric, uneven seams, delamination, and mechanical damage. Where required, samples can undergo temperature exposure, flexibility evaluation, dimensional stability testing, and connection-strength assessment.

    Each production order can be manufactured against an approved drawing or technical specification to maintain consistency between batches.

    Double-Layer Silicone Fiberglass Cloth Duct

    Customization / OEM & ODM

    High-temperature ducting often requires customization because equipment layouts, exhaust temperatures, connection dimensions, and available installation space vary considerably. Yozonetech supports development of double-layer silicone fiberglass ducts according to drawings, samples, or detailed application requirements.

    The customization process starts with confirmation of the operating temperature, airflow, duct diameter, required length, installation route, connection dimensions, and surrounding environment. These factors determine the appropriate fabric grade, silicone coating, wall construction, and reinforcement method.

    Customization options include:

    • Inner diameter and overall length
    • Fiberglass fabric grade and weight
    • Silicone coating formulation and thickness
    • Single or double-layer construction
    • Reinforcement structure
    • Color and surface marking
    • Cuffs, sleeves, clamps, flanges, and end fittings
    • Connection geometry
    • Packaging and private labeling

    For OEM projects, customers can provide an existing duct, engineering drawing, photographs, or equipment interface dimensions. Samples can then be developed for installation and thermal-performance evaluation before the final construction is approved for series production.

    FAQ

    1. What is the advantage of using two fiberglass layers?

    The double-layer structure provides a more robust thermal and mechanical barrier than a single fabric layer. It can improve durability during installation and repeated handling while providing additional protection around hot-air systems.

    2. Is the duct suitable for continuous high-temperature operation?

    It can be designed for continuous elevated-temperature service, but the allowable temperature depends on the silicone formulation, fiberglass specification, airflow, and exposure duration. The actual operating conditions should be provided before selecting the final construction.

    3. Can this duct replace metal exhaust ducting?

    In applications where flexibility is required, it can serve as a flexible connection or duct section. However, rigid metal ducting may remain preferable for long unsupported runs, very high mechanical loads, or applications requiring high structural rigidity.

    4. Can you manufacture special end connections?

    Yes. Cuffs, sleeves, clamps, flanges, and other interface configurations can be customized according to the customer’s equipment dimensions and installation method.

    5. Can the duct be manufactured from a customer sample?

    Yes. We can evaluate a supplied sample or drawing and develop a corresponding double-layer construction, subject to confirmation of the required temperature, dimensions, and application conditions.
