Polyurethane Tube (PU Tube) is a highly flexible, durable, and lightweight tubing solution designed for compressed air, fluid transfer, and pneumatic automation systems. Manufactured from 100% pure polyurethane (either ether-based for hydrolysis resistance or ester-based for abrasion resistance), PU tubes combine excellent mechanical strength with superior flexibility, even in tight bending spaces.

PU tubes are widely used in robotics, packaging, printing, CNC machinery, and pick-and-place systems, where dynamic motion and vibration are common. With an extremely small bending radius, PU tubing is ideal for applications where routing in confined spaces is necessary. The material’s natural elastic memory allows it to return to shape even after repeated stretching or coiling, making it highly durable in long-term applications.

Offered in a wide range of outer diameters (OD) and inner diameters (ID), PU tubes are available in various colors and lengths (typically 50m or 100m rolls) to suit multiple industries and identification needs.

Key Features of Polyurethane Tube (PU Tube):

Material & Design
