The result is a flexible, fire-retardant barrier that reflects radiant heat up to 2000°F and endures direct heat exposure up to 500°F, while resisting chemicals, oil, and grime. It’s designed for easy slip-on installation and made in the USA.\u003c\/p\u003e\n\n\u003ch3\u003eHow does Heat Sheath™ reduce heat exposure to lines and cables?\u003c\/h3\u003e\n\u003cp\u003eThe aluminized outer face reflects radiant heat away from covered components, lowering the heat load they experience. The thick fiberglass insulation then buffers remaining heat, slowing thermal transfer and preserving hose and wire integrity under high-temperature conditions.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminized surface reflects radiant heat up to 2000°F\u003c\/li\u003e\n  \u003cli\u003e19 oz fiberglass insulation provides thermal buffering\u003c\/li\u003e\n  \u003cli\u003eWithstands direct heat contact up to 500°F\u003c\/li\u003e\n  \u003cli\u003eAramid thread maintains seam strength under heat stress\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat kinds of damage does this sleeving prevent?\u003c\/h3\u003e\n\u003cp\u003eHeat Sheath™ addresses multiple failure modes at once — it resists abrasion from vibration and contact, repels oil and fuel that accelerate degradation, and provides flame-retardant coverage to reduce fire risk around hot components.
