Flexcoil PU Tubing (Spiral Polyurethane Pneumatic Tubing)

Flexcoil PU tubing is a spiral polyurethane pneumatic tube designed for applications requiring flexibility and automatic retraction. Compared with straight pneumatic tubing, coiled PU tubing saves space and prevents tangling in dynamic pneumatic systems.

Our polyurethane tubes are made of high quality TPU granules through extrusion process, available in polyester and polyether formulations, both of which are made of non-toxic raw materials. They are extremely resistant to abrasion, tearing, impact and radiation, and have high resilience.

Mainly used in pneumatic systems, hydraulic systems, automated production lines and robotic applications.

● Construction applications

● Motion control devices

Advantages of Polyurethane Over Other Materials

Compared with traditional PVC or rubber air hoses, polyurethane tubing offers several performance benefits.

Polyurethane has significantly better abrasion resistance, allowing it to withstand repeated movement and friction in industrial environments. It also maintains flexibility even at lower temperatures, which helps prevent cracking or hardening during operation.

In addition, polyurethane tubing typically has higher tear strength and longer service life, reducing the frequency of replacement in pneumatic systems.

These properties make PU tubing one of the most preferred materials for modern pneumatic applications.

FAQ

What is flexcoil PU tubing used for?
