The Anti Spark PU Tube is a specialized pneumatic tubing solution designed for environments where exposure to sparks, heat, or occasional flame contact is common—such as welding stations, automotive workshops, and industrial assembly lines. Made from high-quality polyurethane (PU) blended with flame-retardant and spark-resistant additives, this tube combines outstanding flexibility with enhanced safety features to prevent ignition, melting, or wear caused by hot particles or sparks.

Its outer jacket is coated or infused with anti-spark materials that resist surface damage from welding spatter and flying sparks. Unlike standard PU tubes, the anti-spark version is engineered to maintain mechanical integrity under thermal stress, while offering the same flexibility, small bending radius, and pressure-handling capacity as traditional PU tubing.

The anti spark PU tube is available in various standard diameters and roll lengths, and is fully compatible with push-to-connect pneumatic fittings, making it a plug-and-play upgrade in safety-critical pneumatic systems.

Key Features of Anti Spark PU Tube:
