AirTAC PU Tube and PA Tube Guide for RFQ
Compare AirTAC PU tube, AirTAC PA tube, and compatible tube options by flexibility, rigidity, pressure conditions, and fitting compatibility before you move into a bundled quotation.
What This Tube Category Helps You Solve
This page helps buyers choose the right material and size for air-system routing before matching the tubing to fittings and valves.
Flexible Routing
PU tube works well where tighter bends and easier handling are important.
Higher Rigidity
PA tube is often preferred for more rigid layouts and harsher conditions.
Bundle Purchasing
Tubing is commonly quoted together with fittings and valve-related air control parts.
Choose the right tubing path before you compare materials
Tube RFQs can start from original-brand continuity, compatible bundled supply, or application-first replacement comparison.
Original-Brand Path
Use this path when the buyer needs known brand continuity for an existing pneumatic routing setup.
HKQD Compatible Path
Use this path for practical tube sourcing matched to fittings, pressure, and routing requirements.
Replacement Guide Path
Use guides to compare PU and PA logic, fit conditions, and compatible quoting options.
Compare the Main Tube Materials
| Series | Material | Main Benefit | Common Sizes |
|---|---|---|---|
| PU Tube | Polyurethane | Flexible routing and small bending radius | 4 to 16 mm OD |
| PA Tube | Polyamide / nylon | Higher rigidity and pressure resistance | 4 to 12 mm OD |
Where These Tube Types Are Commonly Used
Machine Cabinets
PU tube is useful where routing needs cleaner bends in tighter space.
Factory Air Lines
PA can be preferred where the layout needs more rigid structure or higher resistance.
Valve and Cylinder Linking
Both materials are commonly used between fittings, actuators, and air-control components.
Stock and Replacement Supply
Tube color, roll length, and OD are common buying variables in repeat orders.
What Buyers Usually Confirm Before RFQ
- Confirm whether flexibility or rigidity matters more in the installation
- Match tube OD with fitting series and port requirements
- Review pressure, temperature, bend radius, and routing environment
- Prepare color, roll length, and quantity requirements before RFQ
Best Inputs to Send
For faster matching, send material preference, tube OD, working pressure, routing condition, and which fitting series the tube must match.

Contact UsQuestions Buyers Ask Most Often
What is the difference between PU tube and PA tube?
PU is more flexible and easier to route in compact spaces, while PA is more rigid and often preferred for tougher conditions.
How do I choose the correct tube size?
Tube size depends on flow demand, fitting size, installation space, and system pressure.
Can you supply different colors and roll lengths?
Yes. Common colors and multiple coil lengths are usually available depending on the material and model.
Need Help Matching Tube Material and Size?
Send the required OD, fitting reference, pressure condition, and routing environment so we can suggest the right tube option.
