Loose wires, fuel lines, and hoses routed through a hot engine bay face a constant threat from abrasion, chemical exposure, and radiant heat. The Heatshield Products Hot Rod Split Sleeve bundles and shields those runs with a flame-retardant, self-closing sleeve rated for continuous exposure up to 300°F and intermittent peaks up to 350°F, all while giving the engine bay a clean, organized appearance.
Self-closing, reclosable design. The split-sleeve construction wraps around existing wires and lines without disconnecting anything. Once installed, the sleeve closes on itself and stays put. Every roll includes HP Racer's Tape to seal the ends and deliver an OEM-style finished look.
Triple-threat protection in a single sleeve. The material resists abrasion from vibrating brackets and rough surfaces, stands up to fuel, oil, and chemical contact, and deflects heat that would otherwise degrade wire insulation and hose compounds over time. Consistent protection means fewer surprise failures down the road.
Available in four diameters and three roll lengths. Inside diameters run 3/8", 1/2", 3/4", and 1", with roll lengths of 6 ft, 10 ft, and 20 ft per size. That range covers everything from small wiring harnesses to larger coolant and fuel line runs in a single order.
