Q'ty :

SHPI anti-spark tubing is an integrated dual-layer tubing construction, utilizing a polyurethane (PU) tube as the base medium for compressed air conveyance in pneumatic systems. An outer flame-retardant material layer is incorporated to provide additional surface protection when the tubing is exposed to incidental contact with sparks or weld spatter in environments such as welding operations.

The outer layer material is classified to UL 94 V-0 flammability rating and exhibits self-extinguishing characteristics. UL 94 is a standardized test method for evaluating the flammability behavior of plastic materials, in which the V-0 classification describes the material’s burning response during a vertical burning test after the ignition source is removed. This classification reflects the flammability characteristics of the material itself only.
