Heat Sleeve 3/4in x 3ft Black

The ALLSTAR PERFORMANCE Heat Sleeve 3/4in x 3ft Black is a protective hose and wire sleeve engineered for high-temperature engine bay environments. This 3-foot silicone and fiberglass composite sleeve features a 3/4-inch inner diameter, designed to shield fuel lines, brake lines, spark plug wires, and electrical harnesses from extreme heat, abrasion, and corrosive contaminants. Built for race cars, hot rods, marine engines, and high-performance automotive applications, this heat sleeve provides reliable thermal protection where standard rubber conduit fails.

The dual-material construction combines silicone's heat resistance with fiberglass reinforcement to handle continuous exposure to temperatures that would degrade standard hoses. The black finish blends seamlessly into engine compartments while resisting UV degradation and oil saturation. At 3 feet in length, this sleeve accommodates most common hose routing layouts without requiring multiple pieces. The 3/4-inch ID accepts standard hoses and wiring bundles, providing a snug fit that prevents slippage while maintaining flexibility for routing around engine components and chassis obstacles.

Racers, vintage restoration specialists, and marine engine builders rely on ALLSTAR PERFORMANCE heat sleeves to extend component lifespan in demanding conditions. Whether protecting fuel lines on a carbureted engine, insulating wiring near exhaust manifolds, or shielding brake lines in high-heat engine bays, this sleeve offers proven thermal protection. The 3/4-inch sizing fits the majority of standard automotive line diameters, making this a versatile choice for custom fabrication, engine bay rewiring, or component replacement projects where heat protection is critical.
