Heat Sleeve 1/2in x 3ft Orange

The Heat Sleeve 1/2in x 3ft Orange from ALLSTAR PERFORMANCE is a thermal protection wrap engineered for high-temperature engine components in performance and street-driven vehicles. Whether you're routing fuel lines near exhaust manifolds, protecting hoses in tight engine bays, or shielding wiring harnesses from radiant heat, this heat sleeve provides essential insulation that prevents premature hose degradation, fuel vaporization, and electrical damage. Mechanics and engine builders rely on quality heat protection to extend the longevity of critical fuel delivery and cooling systems, especially in modified engines where underhood temperatures climb significantly above factory specifications.

This 1/2-inch diameter sleeve spans 3 feet of coverage, giving you substantial footage for multiple component protection in a single roll. The bright orange color aids visibility during installation and inspection, allowing you to quickly verify coverage during routine maintenance or future modifications. ALLSTAR PERFORMANCE heat sleeves are constructed from fire-resistant, flexible material that withstands repeated thermal cycling and vibration without cracking or peeling—critical attributes when managing constant temperature swings in turbocharged or supercharged engine environments. The expandable design accommodates hoses and cables with slight diameter variance, simplifying installation and ensuring snug, permanent contact for optimal heat dissipation.

This heat sleeve excels in fuel system protection, particularly for aftermarket fuel injector kits, EFI conversions, and high-flow fuel rails mounted near or routed around hot engine zones. Street racers, LS engine swap builders, and performance enthusiasts working in compact engine compartments find the 3-foot length ideal for protecting braided stainless fuel lines, rubber coolant hoses, and wiring bundles. Installation is straightforward: slip the sleeve over the target component and secure with integrated ties or standard automotive clamps at intervals. Verify clearances before final routing to prevent contact with moving parts or sharp edges; the flexible construction conforms easily but benefits from proper support along its length.
