The result is a flexible, fire-resistant jacket that reflects radiant heat up to 2000°F and endures direct contact temperatures to 500°F while keeping routed lines shielded from wear, grease, and road debris. Its simple slip-on design makes retrofit and repair work fast without specialty tools. Made in the USA, Heat Sheath is intended to protect components from heat sources—do not wrap directly onto exhaust manifolds or pipes.\u003c\/p\u003e\n\n\u003ch3\u003eHow does Heat Sheath keep hoses and wires cooler under high heat?\u003c\/h3\u003e\n\u003cp\u003eHeat Sheath combines reflective and insulative layers to reduce heat transfer by reflecting radiant energy and slowing conductive heat. That keeps the temperature at the hose or cable surface lower, extending life and reducing heat-related failures.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminized outer layer reflects radiant heat up to 2000°F.\u003c\/li\u003e\n  \u003cli\u003e19 oz high-temp fiberglass core provides thermal insulation.\u003c\/li\u003e\n  \u003cli\u003eWithstands direct heat exposure up to 500°F without degrading.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this sleeving resist abrasion, oil, and chemicals in engine bays?\u003c\/h3\u003e\n\u003cp\u003eYes—Heat Sheath’s construction is selected for durability in harsh environments.
