SMC Series TU Compressed Air Pipe, 2.5mm Inside Diameter, 100m Length - TU0425R-100


This compressed Air pipe provides flexible pneumatic tubing for automation and control applications. It is constructed from polyurethane and supplied as a long roll for bulk installation, designed to carry compressed Air in industrial and laboratory settings where flexible, colour-coded tubing is required.

Features & Benefits


• High operating pressure supports up to 0.8MPa for robust system performance
• Wide temperature tolerance functions from -20°C to 60°C for varied environments
• Red colour coding enables fast Visual identification in complex systems
• Long 100m roll reduces jointing and installation time on site
• High-flex material improves routing in confined assemblies

**Applications**


• Suitable for pneumatic control lines in automated assembly equipment
• Ideal for internal Air distribution on production machinery
• Used for lab pneumatic circuits requiring long continuous lengths
• Can be used for signal Air tubing in electrical enclosures
• Used with pneumatic actuators and valves in mechanical systems

What internal flow characteristics can I expect from this tubing?


The bore measures 2.5mm allowing controlled volumetric flow suited to small-bore pneumatic circuits and precise actuator control.

How does the outer size affect fittings selection?


The outside diameter is 4mm so push-fit connectors and fittings sized to that OD should be selected to ensure proper sealing and retention.

Is the material appropriate for repeated flexing during motion?


The polyurethane construction offers high Flex fatigue resistance, making it suitable for applications involving frequent movement or vibration.

What environmental considerations affect long-term use?


Continuous exposure above 60°C or below -20°C will affect mechanical properties, so operation should remain within the specified temperature band.

Are there any regulatory attributes specified for use?


The tubing conforms to RoHS requirements indicating restricted use of certain hazardous substances.
