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.
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.

PA6 / PRODUCT INFORMATION
PA6 Nylon Tubing
Conditional candidate: only where the selected model’s rated working pressure is confirmed for your application.

PA12 Nylon Tubing
Conditional candidate: review PA12 model data separately from PA6 and confirm the rated working pressure for your application.
View specifications →High-pressure tubing questions
What is the maximum operating pressure for nylon tubing?
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.
