PU Pneumatic Tube

Flexible Polyurethane Air Tubing for Pneumatic Systems

Specifications

Tube Material: Nylon and Polyurethane
Fliud Type: Air, Vacuum
Operating Pressure: 1-1.0Mpa

PU pneumatic tube is a flexible and wear-resistant air hose designed for compressed-air transmission in industrial automation systems. Manufactured from quality polyurethane material, it combines excellent flexibility, reliable pressure resistance, a smooth surface, and a small bending radius.

Our PU tubing works with standard pneumatic push-in fittings and is suitable for pneumatic cylinders, solenoid valves, air preparation units, pneumatic tools, packaging machines, assembly equipment, and general factory automation.

A wide selection of tube sizes and colors is available to support different installation requirements and simplify pneumatic circuit identification.

Key Features

Excellent Flexibility

Polyurethane tubing is softer and more flexible than many conventional plastic tubes. It can be routed easily through compact machines, control cabinets, and automation equipment with limited installation space.

Small Bending Radius

The tube can bend around machine components without requiring excessive installation space. Its small bending radius makes it suitable for complex pneumatic circuits and moving applications.

Good Abrasion Resistance

Quality polyurethane material provides excellent resistance to surface abrasion and repeated movement. This helps extend the tube’s service life in demanding industrial environments.

Reliable Air Sealing

The tube features a smooth outer surface and consistent dimensional accuracy. When used with a compatible push-in fitting, it provides a secure connection and helps reduce compressed-air leakage.

Lightweight and Easy to Install

PU air tubing is lightweight and can be cut quickly using a pneumatic tube cutter. It connects directly to standard push-to-connect fittings, reducing installation time and maintenance costs.

Multiple Colors Available

Different tube colors make it easier to identify separate pneumatic circuits, air directions, pressure zones, or machine functions. This improves installation efficiency and simplifies future troubleshooting.
