SMC Compressed Air Pipe Blue Polyolefin, Polyurethane 6 mm 20 m TRBU Series

SMC TRBU Series Compressed Air Pipe, 20m Length, 6mm Outside Diameter - TRBU0604BU-20

This compressed air pipe is designed for conveying air and water in pneumatic and fluid systems where resistance to flame and a flexible polymer construction are required. It is supplied in a continuous 20m length and is suited to installation environments that demand a compact, colour‑coded line.

Features and Benefits:

• Flame‑resistant construction reduces fire risk in confined systems
  Polyurethane and polyolefin materials provide abrasion resistance
  8 bar maximum operating pressure supports moderate‑pressure systems
  Operates continuously between -20°C and 60°C for varied climates
  Single‑tube design simplifies routing in tight assemblies

Applications

• Used for pneumatic control lines in factory automation
  Suitable for low‑volume water distribution in machinery
  Ideal for air supply to actuators and valves
  Can be used for workshop compressed air feed lines
  Used with diagnostic rigs requiring visual line identification

What are the internal and external diameters relevant for fittings?

The bore measures 4mm and the outside dimension is 6mm, so select fittings sized to accept a 4mm ID with 6mm OD clearance.

How does the material selection affect flexibility and wear?

The combination of polyurethane and polyolefin yields a balance of flexibility and surface durability, reducing kinking while resisting abrasion from contact and movement.

What length options are available for installation planning?

This version is provided as a single continuous 20m reel suitable for runs requiring that specific length.

How should the line be used with pressure‑rated equipment?

Ensure system components do not exceed 8 bar working pressure and verify transient pressures remain within that limit to prevent failure.
