Polyurethane Pneumatic Tubing – Ester PU Air Tube


Flexible ester-based polyurethane pneumatic tubing for compressed air, pneumatic control systems and industrial automation.

Manufactured from high-quality polyester polyurethane (Ester PU), this tubing combines excellent flexibility, abrasion resistance and oil resistance with a smooth internal bore for reliable compressed-air flow.

Available in metric sizes from 4mm to 16mm OD, multiple colours and roll lengths from 50 to 200 metres, depending on size and colour.

Material & Performance

Material: Polyester-based polyurethane (Ester PU)
Ester polyurethane provides an excellent combination of flexibility, mechanical strength and abrasion resistance, making it particularly suitable for pneumatic machinery, automation equipment and general compressed-air distribution.

Its flexibility allows tubing to be routed around machinery and through confined spaces while maintaining a relatively tight bend radius.

Available Sizes & Colours

Available in a range of metric outside diameters from 4mm to 16mm, with different internal diameters according to tube size.
Roll lengths range from 50 metres to 200 metres, depending on size and colour.
Available colours include Blue, Black, Red and other options depending on size.
Select the required tubing size, roll length and colour from the product options above.

Typical Applications

✓ Compressed air systems
✓ Pneumatic control circuits
✓ Industrial automation
✓ Machine air distribution
✓ Pneumatic cylinders and valves
✓ Push-in pneumatic fittings
✓ Vacuum circuits
✓ Robotics and moving equipment
✓ General industrial pneumatics

Ester PU or Ether PU – Which Should I Choose?

Ester PU is the preferred general-purpose choice for normal compressed-air applications, particularly in dry indoor industrial environments.
For applications involving water, high humidity, repeated moisture exposure or outdoor installations, our Ether-Based Polyurethane Tubing is generally the better choice due to its improved resistance to hydrolysis and moisture.

Choose Ester PU → General compressed air, machinery, automation and indoor pneumatic systems.

Choose Ether PU → Water, humid environments, outdoor use and applications with repeated moisture exposure.

Installation

Designed for use with standard pneumatic push-in fittings matched to the tubing outside diameter.
For reliable sealing, tubing should be cut cleanly and squarely using a suitable pneumatic tube cutter before insertion into the fitting.

We use this tubing for running fibre optic cable through on new builds, ideal for us has its much cheaper than buying the purposely made tube for the job we need, does not kink and glides straight through. A++++
