SMC Compressed Air Pipe Clear Polyurethane 4 mm 20 m TU Series

This compressed Air pipe is a clear polyurethane tube designed for pneumatic conveyance in industrial environments. It provides a flexible, transparent conduit for conveying compressed Air and is supplied in a continuous 20 m length suitable for installation runs and maintenance spares. The material selection and Visual clarity support monitoring of flow and cleanliness in assemblies where visibility matters.

• Maximum operating pressure 0.8 MPa enabling higher-pressure pneumatic circuits
• Temperature range -20°C to 60°C allowing cold-start and warm-process use
• Polyurethane construction offering flexibility and abrasion resistance
• Clear colour permitting Visual inspection of internal condition
• Outside diameter 4mm enabling Compact routing in restricted spaces
• Inside diameter 2.5mm supporting precise airflow control

• Suitable for pneumatic tubing in automotive assembly cells
• Ideal for compressed Air supply to semiconductor equipment
• Used with food handling lines where transparent tubing is required
• Can be used for medical care pneumatic connections in laboratories
• Suitable for general pneumatic piping in confined spaces

It retains usable flexibility down to -20°C and maintains integrity up to 60°C, reducing the risk of embrittlement in cold conditions and softening at elevated temperatures.

With a 4mm external diameter and 2.5mm bore, it fits small fittings and tight bundling but requires compatible push-fit or clamp connections sized to these diameters.

The small internal bore provides predictable flow resistance for systems requiring controlled Air delivery and quick response in actuators.

Over long continuous runs, cumulative pressure drop and potential for slight dimensional stretch under sustained pressure should be accounted for in system design.
