SMC TRBU0805BU20 (TRBU0805BU-20) - Flame-Resistant Polyurethane Tubing, Ø8 x Ø5, Blue 20 m
SMC TRBU0805BU20 Flame-Resistant Polyurethane Tubing — Ø8 x Ø5, Blue, 20 m. SMC TRBU0805BU-20 is a flame-resistant double-layer polyurethane tubing with Ø8 mm outer diameter and Ø5 mm inner diameter, supplied as a 20 m roll. The blue outer layer is a flame-retardant polyolefin equivalent to UL-94 Standard V-0 over a polyurethane inner tube (inner tubing colour is black). Rated for air and water at a maximum operating pressure of 0.8 MPa (at 20°C), ambient and fluid temperature -20 to 60°C (water 0 to 40°C, no freezing), with a minimum bending radius of 20 mm.

TRBU0805BU-20 Applications
Use SMC TRBU0805BU-20 for air and water piping in areas where sparks from spot welders or similar equipment pose a fire risk. The blue outer layer aids colour-coded line identification while the flame-retardant polyolefin jacket (UL-94 V-0 equivalent) protects the polyurethane core. The 20 m roll suits maintenance, repair and smaller machine builds in welding cells and automated equipment.
