HP Racerfts Tape is a self-emulsifying uncured silicone tape that provides rugged heat protection up to 450F. Wrap up your wire loom or fuel and shield it from heat damage. HP Racer?s Tape can even be used to temporarily fix holes in radiator hoses, lines, etc. for a quick roadside or pit repair. This silicone tape reduces and helps to dissipate radiant heat. Using the guide line to wrap, the tape will stick to itself forming a bond that can only be cut with a knife. The tape does not harden; it remains flexible but will not unravel.
