Build fast, flexible air lines with this polyurethane (PU) pneumatic tube. The smooth-bore round corrugated-free profile delivers low pressure loss and excellent kink recovery for pneumatic tools, automation, instrumentation, and machine air circuits. PU offers high elasticity, abrasion resistance, and a strong memory effect—folded without creases—for clean routing on moving axes and tight spaces.
Key Features & Benefits
- High Flexibility & Memory: Quick bend recovery, minimal kink set; ideal for cable carriers and moving tooling.
- Durable PU Compound: Tough, smooth outer surface resists abrasion and common shop contaminants.
- Low Pressure Loss: Smooth I.D. supports efficient airflow for responsive actuators and valves.
- Wide Temperature Window: −20 to +80 °C (−4 to +176 °F) continuous service.
- Chemical Resistance: Handles oils and many non-corrosive media used in industrial environments.
- Bulk Efficiency: 200 m/roll reduces changeovers and simplifies inventory.

Installation & Use Notes
- Use rated push-to-connect or barb fittings sized to the tube ID/OD; cut ends square for best sealing.
- Pressure/Temp Derating: Reduce allowable pressure as temperature rises; stay ≤ 0.8 MPa at ~20 °C for long life.
- Media: For compressed air & vacuum primarily. Not for drinking water; verify chemical compatibility for any liquids.
- Avoid excessive bend, twist, or tensile loads on fittings; support long vertical runs to prevent creep.
What’s in the Box
- 1 × 200 m roll of PU tube (select OD×ID size)
- Basic handling & safety notes (printed or digital)
Frequently Asked Questions (FAQs)
1) What’s the difference between PU and nylon tubing?
PU is more flexible with better kink recovery and bend radius; nylon is stiffer with higher working pressure and temperature capability.
2) Can I use this for vacuum?
Yes—PU tube supports typical industrial vacuum service. Use adequate wall thickness for your size and support to avoid collapse.
3) Is 145 psi the working or maximum rating?
145 psi (≈1.0 MPa) is the maximum rating at ~20–23 °C. Recommended continuous working pressure is 0.8 MPa (≈116 psi), with temperature derating.
4) Does it handle oils?
Yes—PU is generally resistant to lubricating oils present in compressed-air systems. Verify specific chemical exposure if in doubt.
5) Potable water safe?
No. Not for drinking water. For non-potable water or gardening, ensure ambient temperature and pressure stay within ratings.
6) Which fittings should I use?
Use quality push-to-connect or barbed fittings matched to OD/ID. Always cut square and fully seat; test for leaks at operating pressure.
7) Does the tube “remember” shape after kinking?
Yes—PU has a strong restoring memory and recovers quickly, minimizing flat spots compared with PVC or nylon.
8) Can I run solvents or fuels?
Not recommended. Many fuels/solvents can attack PU. Check compatibility charts or choose a rated material (e.g., PTFE, PA12).
9) How do I size flow capacity?
Choose ID based on required SCFM and run length. Larger IDs reduce pressure drop for long runs or high-flow actuators.
10) Are other colors available?
Standard is black; other colors (blue, red, yellow, etc.) can be produced on request—useful for line color-coding.
