--- title: "High-pressure nylon (PA6, PA12) and composite tubing for equipment lines" canonical: "https://yuannaitube.com/industrial-tubing-applications/high-pressure-equipment-tubing/" language: "en-US" --- [← All industrial tubing applications]() ![AIR PASSAGE FEP tubing product]() HIGH-PRESSURE / EQUIPMENT TUBING # High-pressure nylon (PA6, PA12) and composite tubing for equipment lines Review flexible **high-pressure composite tubing** for equipment lines, with PA6 and PA12 nylon as candidates where the rated **working pressure** is confirmed. Identify the model, construction, medium and fittings; burst pressure is a separate test value. [Discuss your project →]() [View product range →]() **Scope note:** No rated **working pressure** is stated here; burst pressure is a separate test value. QUICK SELECTION ## Four details to confirm before a pressure review Start from the **working pressure** and the complete connection. The selected model’s own limits and test conditions decide suitability; a material name or a burst value does not. ### 1. Medium and exposure The medium, and any coating, solvent or paint exposure that needs substance-specific confirmation. ### 2. Working pressure and temperature **Working pressure** at the stated temperature. Do not use burst pressure as a working value. ### 3. Model and dimensions Model code, ID and OD, length and the construction of the selected tubing. ### 4. Fittings and assembly The complete fitting assembly, and how the line is routed and supported. ## Three questions before specifying pressure tubing 01 ### What is the working pressure? State the **working pressure** at the **operating temperature**. Pressure and temperature ratings are listed separately, and **working pressure** is the design rating while burst pressure is a test value. 02 ### What medium and exposure apply? Identify the medium and any coating, solvent or paint exposure; these require substance-specific confirmation for the selected model. 03 ### How is the line assembled? Confirm the model, layer construction, fitting requirements and the complete assembly before use. Describe how the line is routed and supported. ## Request the construction and model limits Confirm the selected model, layer construction, fitting requirements and the applicable working-pressure conditions before ordering. [Read how to interpret reports →]() ### Confirm for the selected model This page does not give a rated **working pressure** for any family. PA6 and PA12 nylon are candidates only where the selected model’s rated **working pressure** is confirmed for the application.

[View specifications →]() ## High-pressure tubing questions ### What is the maximum operating pressure for nylon tubing? It depends on the model, wall construction and temperature. **Working pressure** is listed per model at 23°C in the [PA6]() and [PA12]() specification tables; confirm it at your **operating temperature** and fittings. Burst pressure is not a working-pressure rating. ### Should I start with PA6 or PA12 for a high-pressure line? Review the PA6 and PA12 models first, using each model’s **working pressure** from its specification table, then compare **composite tubing** for the construction you need. A matching outside diameter does not make nylon interchangeable with **composite tubing**. ### Can composite tubing be used with coatings, solvents or paints? These require substance-specific confirmation for the selected model. State the medium and exposure in the **enquiry**. ### What should a high-pressure tubing inquiry include? Send the medium, **working pressure** and temperature, model or dimensions, length, fitting details and how the line is routed and supported. ### Nylon or polyurethane for air lines? Compare the exact PU and nylon models for the same OD × ID, pressure, temperature and routing; a material name alone does not set the limit. The [PU vs. nylon selection checklist]() lists what to compare. ### PA11 or PA12? This site lists PA6 and PA12 ranges. Specify PA12 together with the model, ID, OD and fittings in your **inquiry**. ## Prepare your project inquiry Send the medium, **working pressure** at temperature, model or ID × OD, length, fittings and quantity. Include how the line is routed and supported.
