PA Tube – PA11 & PA12 Tubing for Oil, Fuel and Vapor Transfer

Product Overview

PA Tube is a high-performance thermoplastic tubing solution designed for applications requiring reliable resistance to oils, fuels, hydrocarbons, abrasion, pressure, and mechanical stress. Manufactured from high-quality polyamide materials, including PA11 and PA12, the Tubo extruido provides an excellent balance of flexibility, chemical resistance, dimensional stability, and long-term service performance.

PA11 and PA12 tubing are widely used in fuel delivery, oil transfer, fuel vapor management, lubrication systems, pneumatic circuits, automotive fluid systems, and industrial equipment. Their relatively low density and excellent mechanical strength make them a practical alternative to heavier metal tubing in many fluid-transfer applications.

Depending on the application, Yozonetech ptfe tube manufacturer can supply PA tubing in different dimensions, wall thicknesses, hardness levels, colors, and performance grades. Material selection can be optimized according to the transported medium, temperature, pressure, flexibility requirements, and applicable industry standards.

PA11 vs. PA12: Which Material Should You Choose?

Although PA11 and PA12 are both high-performance polyamide materials, their characteristics make them suitable for somewhat different application requirements.

PA11 Tube

PA11 is particularly attractive for applications requiring a combination of fuel resistance, flexibility, toughness and long-term mechanical performance. It has been widely used in automotive and industrial fluid systems where the tubing may be exposed to fuels, oils, hydraulic fluids or other hydrocarbon-based media.

PA11 is a strong candidate for fuel lines, fuel vapor systems, oil transfer lines and applications where improved flexibility and resistance to environmental stress are important.

PA12 Tube

PA12 offers excellent dimensional stability, low moisture absorption, chemical resistance and flexibility. It is widely used in pneumatic systems, automotive fluid lines, fuel-related applications and industrial equipment.

Its relatively low moisture absorption compared with some other polyamide materials helps maintain stable mechanical and dimensional properties in changing environmental conditions.

The final choice between PA11 and PA12 should be based on the actual medium, operating temperature, pressure, environmental exposure, installation method and required service life.

Materials & Construction

Yozonetech PA tubing is manufactured through controlled extrusion processes to achieve consistent dimensions and stable wall thickness. The tubing can be produced using PA11, PA12 and other polyamide grades according to application requirements.

For oil and fuel-related applications, the material formulation is particularly important. Tubing performance is influenced not only by the nominal polymer type but also by resin grade, additives, processing conditions, wall thickness and the specific fuel or oil being transported.

For demanding applications, the tubing can be developed with customized formulations or constructions to improve resistance to fuel permeation, temperature, pressure, vibration and environmental exposure.

Black tubing is commonly selected for outdoor and automotive applications because it provides improved protection against UV exposure, while natural or transparent options may be selected when visual inspection of the internal medium is beneficial.

Aplicaciones

PA11 and PA12 tubing can be used across a wide range of fluid and gas-transfer systems.

For applications involving gasoline, diesel, ethanol-blended fuels, fuel vapor or specific hydrocarbons, the tubing should be evaluated against the actual fluid composition and operating conditions.

PA Tubing for Oil & Fuel Vapor Applications

PA11 and PA12 are especially valuable where tubing must handle both liquid hydrocarbons and fuel vapor environments while maintaining mechanical integrity.

In automotive and small-engine systems, tubing may experience continuous exposure to gasoline, diesel, lubricants or fuel vapor together with vibration, temperature changes and mechanical movement. A suitable polyamide tubing can provide a combination of chemical resistance, flexibility and mechanical durability that is difficult to achieve with ordinary general-purpose plastic tubing.

For fuel-vapor applications, however, permeation performance is an important consideration. The correct tubing construction should be selected according to the applicable emission requirements and fuel formulation. For applications involving high ethanol content or special fuel blends, Yozonetech can evaluate the material compatibility and recommend a suitable grade or multilayer construction where required.

Manufacturing & Quality Control

Yozonetech manufactures polyamide tubing using controlled extrusion equipment and standardized production procedures. During production, key parameters including material drying, extrusion temperature, extrusion speed, dimensional accuracy and cooling conditions are monitored to maintain consistent tubing quality.

Each production batch can be inspected for:

• Inner and outer diameter
• Grosor de la pared
• Surface appearance
• Dimensional tolerance
• Dureza
• Resistencia a la tracción
• Alargamiento
• Pressure performance
• Chemical compatibility
• Material consistency

For customized fuel and oil applications, additional testing can be arranged according to the customer’s technical requirements.

PREGUNTAS FRECUENTES

1. What is the difference between PA11 and PA12 tubing?

PA11 generally provides excellent toughness, flexibility and resistance to fuels and hydrocarbons, while PA12 offers excellent dimensional stability, low moisture absorption and chemical resistance. The appropriate choice depends on the actual application.

2. Can PA11 and PA12 tubes be used for gasoline?

They can be suitable for certain gasoline and fuel applications, but compatibility depends on the exact fuel formulation, temperature, pressure, exposure time and tubing construction. The actual fuel should be specified when selecting the material.

3. Can PA tubing be used for ethanol-blended gasoline?

PA tubing can be designed for certain ethanol-containing fuels, but compatibility should not be assumed solely from the PA11 or PA12 designation. For E10, E20, E30 or higher ethanol blends, the exact formulation and required permeation performance should be evaluated before production.

4. Is PA tubing suitable for fuel vapor?

Yes, PA11 and PA12 can be used in selected fuel vapor, vent and emission-control applications. Where low fuel permeation is required, a specialized grade or multilayer construction may be more appropriate.

5. Can you manufacture customized PA tubing?

Yes. We can customize material grade, inner diameter, outer diameter, wall thickness, hardness, color, length and packaging according to your technical requirements and application conditions.
