The combination reduces heat transfer, shields vulnerable components from contaminants, and resists wear from chafing and road debris. It's engineered for straightforward installation and long service life while being manufactured in the USA.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this sleeving reduce heat exposure to hoses and wires?\u003c\/h3\u003e\n\u003cp\u003eThe aluminized outer layer reflects intense radiant heat away from protected components, while the thick fiberglass core provides thermal resistance to conduction. Together they lower the amount of heat that reaches hoses and wiring without adding rigid bulk, helping parts run cooler in high-heat zones.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReflects radiant heat up to 2000°F to deflect intense sources.\u003c\/li\u003e\n  \u003cli\u003eWithstands direct contact heat up to 500°F for short durations.\u003c\/li\u003e\n  \u003cli\u003e19 oz fiberglass core slows conductive heat transfer.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it resist abrasion, chemicals, and oil in automotive use?\u003c\/h3\u003e\n\u003cp\u003eYes—Heat Sheath is designed to withstand mechanical wear and common automotive contaminants.
