A PU pneumatic tube is a flexible air tubing made from polyurethane, designed for efficient and reliable compressed air transmission in pneumatic systems. Known for its excellent flexibility and durability, PU tubing is widely used in modern automation and industrial equipment.

Compared to traditional materials such as PVC or rubber, polyurethane tubes offer superior flexibility, abrasion resistance, and long service life, making them ideal for applications that require frequent movement and bending.

Key Features

High Flexibility: Easily bends and routes in complex systems.

Anti-Kink Performance: Maintains airflow even under bending conditions.

Excellent Abrasion Resistance: Withstands dragging and mechanical wear.

Stable Pressure Performance: Ensures consistent compressed air delivery.

Lightweight Design: Improves installation efficiency and handling.

Long Service Life: Resistant to cracking and aging.
