Design Engineering Heat Sheath GOLD™ – 1/2" I.D. x 36" High-Temperature Line Sleeving | Reflects Radiant Heat up to 800°F

Design Engineering Heat Sheath GOLD™ provides advanced protection for hoses, lines, wiring, and air intake components exposed to high heat and abrasion. Manufactured from a high-temperature gold metalized polyimide laminated to a robust 20 oz heat-treated fiberglass base, it reflects up to 90% of damaging radiant heat and withstands temperatures up to 800°F to help keep critical components cool and flexible. Reinforced with aramid fiber thread, Heat Sheath GOLD™ offers excellent abrasion resistance, flame-retardant performance, and long-term durability in demanding automotive and industrial environments. Designed for quick slip-on installation, it delivers professional-grade thermal protection and is proudly made in the USA.

• EXTREME HEAT & ABRASION PROTECTION – Protects hoses, fuel lines, wiring, air intakes, and cables from heat damage, friction, and wear that cause premature failure.
• REFLECTS UP TO 90% OF RADIANT HEAT (800°F) – Gold metalized polyimide outer layer reflects up to 90% of damaging radiant heat and withstands temperatures up to 800°F, helping keep components cooler.
• KEEPS LINES COOL & FLEXIBLE – Maintains hose and line flexibility while resisting abrasion in high-heat automotive and industrial applications.
• EASY SLIP-ON INSTALLATION – Simply disconnect the line or hose, cut to length, slide on, and reinstall—no special tools required.
• HEAVY-DUTY GOLD METALIZED CONSTRUCTION – Precision-engineered using high-temperature gold metalized polyimide bonded to a 20 oz heat-treated fiberglass base for superior thermal protection.
