Design Engineering Heat Sheath Aluminized Sleeving – 1-1/4" I.D. x 3 ft

Design Engineering Heat Sheath™ Aluminized Sleeving provides reliable protection for hoses, wires, cables, and fluid lines exposed to extreme heat and abrasion. Constructed from 19 oz high-temperature fiberglass insulation bonded to a durable aluminized outer layer, it reflects radiant heat up to 2000°F while withstanding direct heat up to 500°F. Reinforced with aramid fiber thread, Heat Sheath delivers excellent abrasion resistance, flame-retardant performance, and long-term durability, while also shielding components from oil, fuel, chemicals, dirt, grease, and road debris. Designed for easy slip-on installation, it helps keep lines cooler, flexible, and protected in demanding automotive and industrial environments. Proudly made in the USA. Do not apply directly to exhaust components.

• EXTREME HEAT & ABRASION PROTECTION – Protects hoses, fuel lines, wiring, and cables from heat damage, friction, and wear that lead to premature failure.
• REFLECTS RADIANT HEAT UP TO 2000°F – Aluminized outer layer reflects intense radiant heat while withstanding direct heat up to 500°F, helping maintain cooler operating temperatures.
• PROTECTS AGAINST OIL, CHEMICALS & DEBRIS – Shields lines and hoses from oil, fuel, chemicals, dirt, grease, and road grime commonly found in automotive and industrial settings.
• EASY SLIP-ON INSTALLATION – Simply disconnect the line or hose, cut to length, slide on, and reinstall—no special tools required.
• HEAVY-DUTY, FIRE-RESISTANT CONSTRUCTION – Built with 19 oz high-temperature fiberglass insulation bonded to a durable aluminum outer layer for long-lasting thermal protection.
