SMC Compressed Air Pipe Red Polyurethane 4 mm Outside Diameter 2.5 mm Inside Diameter 20 m Length TU0425R-20

SMC TU0425R-20 Compressed Air Pipe is a high-quality polyurethane tube designed for pneumatic and fluid power applications in industrial settings. Featuring a 4 mm outside diameter and 2.5 mm inside diameter, this pipe ensures efficient and controlled airflow in pneumatic actuator lines.

Constructed from polyurethane, the pipe offers excellent flexibility and enhanced abrasion resistance compared to many elastomer hoses, making it ideal for environments involving repeated flexing and contact with routed surfaces.

It has a maximum operating pressure of 0.8 MPa, supporting standard pneumatic system demands. The pipe withstands a temperature range from -20°C to 60°C, allowing use in both low-temperature installations and moderately high heat environments.

The bright red coloration aids quick identification of compressed air lines during maintenance and troubleshooting tasks, especially within dense hose and cable bundling typical of control panels and factory automation systems.

Supplied as a continuous 20 m roll, the pipe can be cut to on-site requirements and joined using standard push-fit or compression fittings, providing secure, leak-resistant pneumatic connections.

Applications include pneumatic tubing for automation factories, connection to solenoid valves, air cylinders in control panels, pneumatic instrumentation lines in assembly machinery, and low-temperature pneumatic needs such as cold stores. Its small outside diameter allows compact panel installations where space is limited.

This polyurethane Compressed Air Pipe offers flexibility and abrasion resistance for industrial pneumatic lines. Maximum pressure rating of 0.8 MPa suits typical pneumatic control systems. Operating temperature range from -20°C to 60°C extends its utility in various environments.

Red color facilitates easy visual differentiation of air lines during maintenance. Continuous 20 m length allows bespoke installation cuts and secure push-fit joints. Compact 4 mm outside diameter supports routing in confined spaces and dense assemblies.

Ideal for factory automation, pneumatics instrumentation, and low-temperature pneumatic tubing.
