It reflects radiant heat up to 2000°F and resists direct contact heat up to 500°F while offering splash and abrasion protection against oil, fuel, chemicals, dirt, grease, and road debris. The sleeving is designed for simple slip-on installation and is manufactured in the USA. Note: do not wrap the Heat Sheath directly onto exhaust headers or pipes.\u003c\/p\u003e\n\n\u003ch3\u003eHow does Heat Sheath protect hoses and wiring from heat?\u003c\/h3\u003e\n\u003cp\u003eThe aluminized outer layer reflects radiant heat away from the covered component, reducing thermal load on hoses and wires.
