SMC TU/TIUB Series Hose Pipe, 20m Length, 2.5mm Inside Diameter - TU0425Y-20


This hosepipe is a flexible polyurethane conduit designed to deliver compressed Air in industrial control and automation systems. It is intended for use in pneumatic assemblies and fluid-transfer arrangements where a resilient, lightweight tubing is required, and performs across a broad ambient temperature range suited to typical factory and equipment-room environments.

Features & Benefits


• High-pressure capability up to 8 bar for demanding pneumatic circuits
• Operates from -20°C to 60°C for versatile environmental use
• Polyurethane composition resists abrasion for extended service life
• Certified to CE, UL/CSA and RoHS for regulated installations
• Yellow colour improves visibility for routing and maintenance

**Applications**


• Suitable for pneumatic actuators in automation lines
• Ideal for Air supply to sensors and valve islands
• Used with compressors for localised tool feeds
• Can be used for interconnections on production machinery
• Suitable for wiring conduits where abrasion is a concern

What internal and external diameters are available for fitting choices?


The tubing has an internal bore of 2.5mm and an external diameter of 4 mm, enabling compatibility with standard 2.5mm barbed fittings and easy selection of clamp sizes.

How long is the supply length for installation planning?


The product is supplied in a continuous 20 m length, allowing long runs or multiple branch connections from a single reel.

Which material properties affect flexibility and handling?


The polyurethane material offers a balance of elasticity and stiffness that maintains shape under pressure while remaining easy to route in confined assemblies.

How does the colouring assist in maintenance workflows?


The yellow finish provides Rapid Visual identification of pneumatic lines during troubleshooting and preventative maintenance without additional labelling.
