PU (polyurethane) pneumatic tubing is designed for compressed air applications, including use with air compressors, air pumps, and pneumatic tools. It is available in a variety of colors—transparent, red, blue, and black—with outer diameters ranging from 4 to 16 mm and inner diameters from 2.5 to 12 mm. Lengths can be customized to your requirements (from 10 to 200 meters). Made from PU material, this tubing offers excellent pressure resistance, flexibility, and wear resistance, making it an ideal choice for pneumatic systems. Product Specifications

Installation Instructions

Cut the air tubing to the required length based on your equipment's needs.

Connect using push-to-connect fittings or other pneumatic connectors.

Ensure that the fittings are compatible with the specifications of the air tubing.

After installation, check all connection points for air leaks.

Precautions

⚠️ Do not exceed an operating pressure of 1.0 MPa.

⚠️ Do not exceed an operating temperature of 60°C; keep away from high-temperature heat sources.

⚠️ Avoid contact with sharp objects to prevent scratching or damaging the tubing.

⚠️ Slight color variations may occur between different production batches.

⚠️ Select the appropriate tubing size based on the actual operating pressure.

⚠️ Periodically inspect the tubing for signs of aging after long-term use and replace it promptly if necessary.
