They can help prevent vapor lock and fuel evaporation, increase the efficiency of intercoolers and air conditioners, shield your wiring harnesses and spark plug wires against heat damage, and even keep your intake charge cool. For additional heat protection consider including heat shield material.

Techflex FireFlex Sleeving

Silicone-jacketed fiberglass Techflex FireFlex sleeving is the choice of professionals in racing and other industries where protection from constant temperatures approaching 500 degrees F is mandatory. FireFlex sleeving is engineered to protect hoses, cables, and wire harnesses from damage due to exposure to extreme heat, open flame, molten splash, and welding sparks. The thick, high-temperature fiberglass sleeve is jacketed with a non-permeable, heavy silicone coating that is flexible enough to follow tight radius curves. FireFlex resists all automotive chemicals and solvents, and provides a substantial level of abrasion and puncture protection. Techflex FireFlex sleeving is completely non-conductive, will not melt, delaminate, become brittle, or support combustion under normal conditions. It provides a professional level solution to thermal protection needs in any application.
