Polyurethane tube bends tightly without kinking or collapsing, ideal for moving, flexing, and confined-space pneumatic runs.
Sized for push-in (one-touch) pneumatic fittings — the tube is simply pushed in and gripped, for fast, tool-free assembly and re-routing.
Blue, yellow, red, and black tube lets each air, vacuum, or fluid line be identified at a glance, simplifying installation and maintenance.
PU, nylon, PE, PVC, and PTFE so the tube can be matched to the pressure, temperature, flexibility, and chemical demands of the line.
OD 4 to 16 mm in 10, 20, 50, and 100 m coils and multiples — from fine pilot lines to high-flow main feeds.
Precision-extruded to a consistent bore and wall for reliable sealing in push-in fittings and predictable flow.

Q1. What is PU pipe?
PU pipe is flexible, small-bore pneumatic tubing — most commonly made of polyurethane — used to carry compressed air, vacuum, and low-pressure fluids between compressors, valves, cylinders, and tools. It connects to push-in (one-touch) pneumatic fittings for fast, tool-free assembly and is supplied in colour-coded coils.
Q2. What materials is the tubing available in?
Polyurethane (PU), nylon (polyamide), polyethylene (PE), PVC, and PTFE. PU is the most flexible and kink-resistant for general pneumatics; nylon handles higher pressures and temperatures; PE and PVC are economical for low-pressure fluid lines; PTFE suits aggressive chemicals and high temperatures.
Q3. What sizes and pressure rating are available?
Tube is available from OD 4 mm to 16 mm (ID 2.5 mm to 12 mm), rated up to 10 kg/cm² (about 10 bar) depending on material and size, with a working temperature of 20°C to 80°C for standard materials (PTFE handles higher temperatures).
Q4. What do the tube colours mean?
Colours (blue, yellow, red, black, and natural/clear) are used for line identification — for example separating air supply, vacuum, and control or different machine functions. There is no fixed industry standard, so colours are assigned to suit the plant; consistent coding speeds installation and troubleshooting.
Q5. How is PU tube connected?
Most commonly with push-in (one-touch) pneumatic fittings: the tube is cut square and pushed into the fitting, where a collet grips it and an O-ring seals on the tube OD. To release, the collet ring is pressed and the tube withdrawn. Barb/hose-tail connections are also used. See our PU fittings page.
Q6. Why must the tube be cut square?
A square, clean, burr-free cut lets the O-ring in a push-in fitting seal evenly around the tube OD and the collet grip uniformly. An angled or crushed end causes air leaks and can pull out under pressure. Always use a proper tube cutter rather than pliers or a knife.
Q7. What coil lengths are supplied?
Standard coils of 10 m, 20 m, 50 m, and 100 m, and multiples thereafter. Coil length is chosen to suit the run and to minimise joints, since fewer connections mean fewer potential leak points.
Q8. Can the tube be used for fluids and water, not just air?
Yes. While PU and nylon are most common for compressed air, PE and PVC are widely used for low-pressure water and fluid lines, and PTFE for aggressive chemicals and high temperatures. Select the material for the medium, pressure, and temperature of the line.
