PTFE Etching Tubing OEM Manufacturer for Medical

Medical Tubing Extrusion Product Description

PTFE often needs to be mixed with other materials, but due to its famous smooth surface, it is difficult to combine with other materials. The purpose of fluoropolymer etching is to change the surface characteristics of PTFE, after treatment, it can be combined with other materials, whether it is plastic, metal, composite material or ceramic.

The inherent bonding of fluoropolymers results in extremely low friction. In its unchanged state, the bonds of these polymers are so stable that it is difficult for them to bond with anything, even for a short period of time. When the etching process changes the carbon-fluorine bond of the PTFE bottom layer, the surface of the PTFE changes. After the PTFE is etched, its surface will have more friction, and it can be glued, molded or glued to other materials. It also allows the PTFE tube to be printed or engraved.

YOZONE-Technology provides the following key solutions for PTFE, FEP, PFA and PEEK products. So, today we will introduce you our quality Extruded Tube below:

PTFE tube supplier Extruded tubing is a versatile and widely used product in various industries. It is a continuous length of material that is formed by forcing it through a die, resulting in a hollow cylindrical shape.

A PTFE tube pressure rating must be specified for the selected ID, OD, wall thickness, temperature and fitting arrangement. Request the permitted working pressure for your exact tube. Do not apply the PFA or FEP pressure charts to PTFE tubing. The temperature capability of the polymer also does not authorize pressurized service at the maximum temperature.

Standard Flexible Tubing Dimensions

All dimensions below are in millimeters. ID means inner diameter; OD means outer diameter. Wall thickness is calculated as (OD − ID) ÷ 2. The catalog lists these sizes in its common fluoropolymer tubing table and refers the PTFE flexible tube range to that table. Confirm the PTFE material and dimensional tolerance when ordering.

Packaging and Color Options

Catalog packaging options include 10 m, 20 m, 30.4 m, 50 m, 100 m and 500 m rolls, plus 2 m straight lengths. Availability depends on the selected tube size and construction. Specify whether your production process needs continuous rolls, straight pieces or custom cut lengths.

The shared tubing table lists transparent, semitransparent, white, red, blue, black, yellow, green and multicolor options across PTFE, FEP and PFA. PTFE is typically associated with a milky white or semitransparent appearance in the catalog. Confirm the achievable color and appearance for the chosen PTFE grade; transparent options in the shared table should not be interpreted as a promise of clear PTFE.

Dimensional Ordering

Always state which diameter comes first. Metric flexible sizes here use ID × OD; rigid tube dimensions on the following pages use OD, ID and wall thickness in separate columns. For custom production, provide tolerances for both diameters, cut length, end finish and any inspection requirements.

Applications and Selection

Industrial Chemical Transfer

PTFE tubing is a candidate for industrial lines exposed to chemically demanding media. Select the tube around the actual fluid and concentration, including any cleaning chemicals. Chemical resistance alone does not determine whether a tube is suitable: pressure, permeation, temperature and connection integrity also matter. Send the full operating conditions for technical review.

Electrical and Electronic Insulation

Small bore PTFE tubing can serve as an insulating sleeve around wires or components when its dimensions and electrical performance match the design. Low water absorption and the catalog electrical reference data support this selection process. Required voltage performance must be verified for the finished wall thickness and assembly.

Laboratory and Analytical Equipment

PTFE tubing may be considered for reagent transfer and protective sleeves in laboratory equipment. Specify bore size, routing, dead volume constraints and connection dimensions. Applications sensitive to contamination should define cleanliness, extractables and packaging requirements separately rather than assuming that every standard industrial tube meets them.

Machinery and Protective Components

Rigid PTFE tubes provide hollow stock for sleeves, spacers or other components where a tubular starting shape is useful. Select enough wall thickness for the final geometry and machining allowance. Review mechanical loading, dimensional stability and friction behavior under the actual operating conditions.

Semiconductor and Medical Equipment Selection

For semiconductor applications, define purity, particle and contamination requirements before selecting a grade. Standard PTFE tubing is not automatically qualified for high purity chemical delivery. For medical equipment, consider only appropriately reviewed external or nonpatient contact functions: this catalog specifically prohibits direct contact with biological tissues or fluids and use inside the human body. Medical contact applications require a separately qualified product and supporting evidence.

Choosing the Tube Construction

Flexible tubing is suited to installations that need routing flexibility and a small outside diameter. Rigid tubing is intended for layouts or components that benefit from a stiffer tubular form. Neither construction should be selected solely by name. Check the actual size, allowable pressure, installation geometry and joint design.

Capillary tubing, spiral cut tubing, corrugated tubing, heat shrink tubing and braided hose are separate product constructions. Their own size tables and performance data should be used when those functions are required; a smooth tube specification does not qualify them interchangeably.

Custom Production and Quality Requirements

Yozonetech manufactures standard and customized polymer products according to drawings and agreed specifications. Our company capabilities include extrusion, injection molding, blow molding and CNC machining or turning across the wider product range. Our quality management systems include ISO 9001 and ISO 45001.

Custom Specifications

For a custom PTFE tube, provide ID, OD, wall thickness, length and dimensional tolerance. Add resin grade requirements, color, surface condition, end finish and preferred packaging. For a machined rigid component, include a drawing with critical features, datum references and the inspection method needed for those features.

Inspection and Documentation

Agree the inspection plan before production. Relevant items may include diameter and wall measurements, ovality, length, visible defects, end condition and identification. If pressure performance is required, specify the test conditions and acceptance criteria for the finished tube and its intended fittings. Material documentation, certificates and any application specific reports should be confirmed at quotation stage.

A polymer property table is useful for initial selection, but it does not replace a batch test report or finished product qualification. Any requirement for food contact, biocompatibility, flame testing, restricted substances or special cleanliness must be tied to the actual grade and supplied product.

Installation and Use

Use the product only for its agreed application and within the confirmed service temperature and pressure limits. Allow a routing radius that avoids flattening or kinking, and confirm bend performance for the exact tube. Do not use another material’s bend radius table as a PTFE specification.

Support the tube to prevent strain at connections. Use fittings compatible with the chosen tube material and dimensions, and confirm the assembled system rating. Review the line after repeated use for abrasion, damage, hardening, dimensional change or signs of leakage. The catalog recommends periodic replacement where recurring friction may cause deterioration.

For acids, alkalis and highly hazardous media, consult technical personnel and confirm suitability before use. Keep tubing away from fire and welding. Processing above the stated maximum service temperature may release fluoropolymer decomposition gases; maintain adequate ventilation and follow the product safety data sheet. Dispose of used material in accordance with applicable local requirements.

Request a PTFE Tube Quotation

Send your required quantity, ID and OD or drawing, length, tolerances, color and packaging. Include the medium, concentration, normal and maximum temperature, working pressure and fitting type. For equipment qualification, add the standards and reports required. We can then review the specification and confirm supply details.

Frequently Asked Questions

1 What is PTFE tubing used for

PTFE tubing is used where chemical resistance, insulation or low friction is needed. Candidate applications include industrial fluid lines, insulating sleeves, laboratory equipment and protective components. Confirm the tube against the actual service conditions.

2 What is the difference between flexible and rigid PTFE tubes

Flexible tubing allows easier routing, while rigid tubes provide a stiffer tubular form and can serve as stock for components. Size, wall thickness and construction determine practical behavior, so compare the exact product specifications.

3 Which standard metric sizes are available

The common flexible tubing table lists ID values from 0.3 to 33 mm and OD values from 0.6 to 38 mm. The rigid tube table spans OD 9.5 to 508 mm. These are listed catalog options, with nonstandard dimensions available for review.

4 Can you supply inch sizes

Yes. Catalog options include 1/8, 1/4, 3/8, 1/2, 3/4 and 1 inch outside diameters, plus larger entries. Specify both OD and ID because a nominal inch diameter alone does not define the bore or wall thickness.

5 What is the maximum operating temperature

The material reference table lists 260°C as the maximum continuous operating temperature. Confirm the finished tube service limits for its load, pressure and installation. The melting point of 320–327°C is not an operating temperature.

6 What working pressure can PTFE tubing withstand

There is no single rating covering this entire range. Working pressure must be confirmed for the actual tube dimensions, material, service temperature and fittings. Provide those details when requesting a quotation.

7 Are the listed material properties guaranteed for every tube

No. The catalog states that technical performance data are experimental reference values rather than guaranteed limits. Required properties and acceptance criteria must be agreed for the supplied product.

8 Is this PTFE tubing suitable for direct medical contact

The catalog prohibits contact with biological tissues or fluids and use inside the human body. Do not use this standard industrial range for direct patient contact. Such applications need a separately qualified product and documentation.

9 Can dimensions and colors be customized

Nonstandard sizes and special lengths can be reviewed. Color availability should be confirmed for PTFE rather than inferred from the shared PTFE, FEP and PFA color list. State the desired appearance and tolerances in your inquiry.

10 How is the tubing packaged

Catalog options include rolls of 10, 20, 30.4, 50, 100 and 500 meters and 2 meter straight lengths. Confirm the packaging option for your selected size, or request custom cut lengths and protective packaging requirements.

Air pressure detection — PTFE Customized Flexible Extruded Smooth Bore Tubing OEM Manufacturer

Product Overview

Yozonetech supplies PTFE tubing and rigid PTFE tubes for customers who need chemical resistance, thermal stability, electrical insulation and low friction. Our range covers small bore flexible tubing, standard metric and inch dimensions, and thick wall or large diameter rigid tubes. Nonstandard dimensions and special lengths can be customized to match drawings and application requirements.

PTFE stands for polytetrafluoroethylene. Its combination of chemical resistance and low surface friction makes it useful in industrial transfer lines, insulating sleeves and protective components. The right tube depends on the medium, temperature, pressure, installation space and connection method. We help customers turn those requirements into an agreed specification.

Product Highlights

Chemical resistance

The catalog rates PTFE chemical solvent resistance as excellent. Confirm compatibility with the actual medium, concentration and operating conditions before use.

Temperature capability

The material table lists a maximum continuous operating temperature of 260°C. This is a material reference and does not establish a pressure rating at that temperature.

Low friction

A reference coefficient of friction of 0.02 against steel supports applications where low surface drag is useful.

Electrical insulation

Reference dielectric constant is 2.1 at both 10³ Hz and 10⁵ Hz, with high volume and surface resistivity.

Low water absorption

The listed 24 hour water absorption is below 0.01 percent, helping limit moisture uptake.

Choice of dimensions

Flexible sizes, inch sizes and rigid tube dimensions allow selection around flow requirements, insulation clearance and component geometry.

Applications and Selection

Industrial Chemical Transfer

PTFE tubing is a candidate for industrial lines exposed to chemically demanding media. Select the tube around the actual fluid and concentration, including any cleaning chemicals. Chemical resistance alone does not determine whether a tube is suitable: pressure, permeation, temperature and connection integrity also matter. Send the full operating conditions for technical review.

Electrical and Electronic Insulation

Small bore PTFE tubing can serve as an insulating sleeve around wires or components when its dimensions and electrical performance match the design. Low water absorption and the catalog electrical reference data support this selection process. Required voltage performance must be verified for the finished wall thickness and assembly.

Laboratory and Analytical Equipment

PTFE tubing may be considered for reagent transfer and protective sleeves in laboratory equipment. Specify bore size, routing, dead volume constraints and connection dimensions. Applications sensitive to contamination should define cleanliness, extractables and packaging requirements separately rather than assuming that every standard industrial tube meets them.

Machinery and Protective Components

Rigid PTFE tubes provide hollow stock for sleeves, spacers or other components where a tubular starting shape is useful. Select enough wall thickness for the final geometry and machining allowance. Review mechanical loading, dimensional stability and friction behavior under the actual operating conditions.

Semiconductor and Medical Equipment Selection

For semiconductor applications, define purity, particle and contamination requirements before selecting a grade. Standard PTFE tubing is not automatically qualified for high purity chemical delivery. For medical equipment, consider only appropriately reviewed external or nonpatient contact functions: this catalog specifically prohibits direct contact with biological tissues or fluids and use inside the human body. Medical contact applications require a separately qualified product and supporting evidence.

Choosing the Tube Construction

Flexible tubing is suited to installations that need routing flexibility and a small outside diameter. Rigid tubing is intended for layouts or components that benefit from a stiffer tubular form. Neither construction should be selected solely by name. Check the actual size, allowable pressure, installation geometry and joint design.

Capillary tubing, spiral cut tubing, corrugated tubing, heat shrink tubing and braided hose are separate product constructions. Their own size tables and performance data should be used when those functions are required; a smooth tube specification does not qualify them interchangeably.

Custom Production and Quality Requirements

Yozonetech manufactures standard and customized polymer products according to drawings and agreed specifications. Our company capabilities include extrusion, injection molding, blow molding and CNC machining or turning across the wider product range. Our quality management systems include ISO 9001 and ISO 45001.

Custom Specifications

For a custom PTFE tube, provide ID, OD, wall thickness, length and dimensional tolerance. Add resin grade requirements, color, surface condition, end finish and preferred packaging. For a machined rigid component, include a drawing with critical features, datum references and the inspection method needed for those features.

Inspection and Documentation

Agree the inspection plan before production. Relevant items may include diameter and wall measurements, ovality, length, visible defects, end condition and identification. If pressure performance is required, specify the test conditions and acceptance criteria for the finished tube and its intended fittings. Material documentation, certificates and any application specific reports should be confirmed at quotation stage.

A polymer property table is useful for initial selection, but it does not replace a batch test report or finished product qualification. Any requirement for food contact, biocompatibility, flame testing, restricted substances or special cleanliness must be tied to the actual grade and supplied product.

Installation and Use

Use the product only for its agreed application and within the confirmed service temperature and pressure limits. Allow a routing radius that avoids flattening or kinking, and confirm bend performance for the exact tube. Do not use another material’s bend radius table as a PTFE specification.

Support the tube to prevent strain at connections. Use fittings compatible with the chosen tube material and dimensions, and confirm the assembled system rating. Review the line after repeated use for abrasion, damage, hardening, dimensional change or signs of leakage. The catalog recommends periodic replacement where recurring friction may cause deterioration.

For acids, alkalis and highly hazardous media, consult technical personnel and confirm suitability before use. Keep tubing away from fire and welding. Processing above the stated maximum service temperature may release fluoropolymer decomposition gases; maintain adequate ventilation and follow the product safety data sheet. Dispose of used material in accordance with applicable local requirements.

Request a PTFE Tube Quotation

Send your required quantity, ID and OD or drawing, length, tolerances, color and packaging. Include the medium, concentration, normal and maximum temperature, working pressure and fitting type. For equipment qualification, add the standards and reports required. We can then review the specification and confirm supply details.

Frequently Asked Questions

1 What is PTFE tubing used for

PTFE tubing is used where chemical resistance, insulation or low friction is needed. Candidate applications include industrial fluid lines, insulating sleeves, laboratory equipment and protective components. Confirm the tube against the actual service conditions.

2 What is the difference between flexible and rigid PTFE tubes

Flexible tubing allows easier routing, while rigid tubes provide a stiffer tubular form and can serve as stock for components. Size, wall thickness and construction determine practical behavior, so compare the exact product specifications.

3 Which standard metric sizes are available

The common flexible tubing table lists ID values from 0.3 to 33 mm and OD values from 0.6 to 38 mm. The rigid tube table spans OD 9.5 to 508 mm. These are listed catalog options, with nonstandard dimensions available for review.

4 Can you supply inch sizes

Yes. Catalog options include 1/8, 1/4, 3/8, 1/2, 3/4 and 1 inch outside diameters, plus larger entries. Specify both OD and ID because a nominal inch diameter alone does not define the bore or wall thickness.

5 What is the maximum operating temperature

The material reference table lists 260°C as the maximum continuous operating temperature. Confirm the finished tube service limits for its load, pressure and installation. The melting point of 320–327°C is not an operating temperature.

6 What working pressure can PTFE tubing withstand

There is no single rating covering this entire range. Working pressure must be confirmed for the actual tube dimensions, material, service temperature and fittings. Provide those details when requesting a quotation.

7 Are the listed material properties guaranteed for every tube

No. The catalog states that technical performance data are experimental reference values rather than guaranteed limits. Required properties and acceptance criteria must be agreed for the supplied product.

8 Is this PTFE tubing suitable for direct medical contact

The catalog prohibits contact with biological tissues or fluids and use inside the human body. Do not use this standard industrial range for direct patient contact. Such applications need a separately qualified product and documentation.

9 Can dimensions and colors be customized

Nonstandard sizes and special lengths can be reviewed. Color availability should be confirmed for PTFE rather than inferred from the shared PTFE, FEP and PFA color list. State the desired appearance and tolerances in your inquiry.

10 How is the tubing packaged

Catalog options include rolls of 10, 20, 30.4, 50, 100 and 500 meters and 2 meter straight lengths. Confirm the packaging option for your selected size, or request custom cut lengths and protective packaging requirements.
