Hot Rod Sleeve 3/8 in id x 10 ft

The HEATSHIELD PRODUCTS Hot Rod Sleeve 3/8 in ID x 10 ft is a high-temperature fiberglass hose and wire protective sleeve designed to shield critical components from extreme heat in marine and automotive applications. With a temperature rating of 1100 degrees Fahrenheit, this black fiberglass sleeve provides reliable insulation for fuel lines, hydraulic hoses, wiring harnesses, and other engine compartment components exposed to engine heat, exhaust proximity, or welding operations.

The 3/8-inch inner diameter accommodates standard marine hose sizes and electrical wire bundles, while the 10-foot continuous roll provides flexibility for custom routing and multiple installation points. Fiberglass construction offers superior thermal resistance compared to fabric-wrapped or rubber alternatives, maintaining structural integrity even when exposed to prolonged high temperatures. This material is non-conductive, adding an extra layer of safety when routing lines near electrical systems or sensitive marine electronics.

This sleeve is essential for boat builders, marine mechanics, and engine builders who need to protect fuel delivery systems, coolant lines, and wiring from the intense heat found in tightly packed engine bays or around exhaust manifolds. Boaters performing custom installations or upgrading to performance engines benefit from the thermal protection that reduces fire risk and extends the service life of hoses and electrical insulation. The black finish blends into engine compartments while providing UV resistance for long-term outdoor storage and marine salt-air environments.

Hot Rod Sleeve by HEATSHIELD PRODUCTS is a standard choice for marine engine applications where heat management is critical. The 10-foot length allows technicians to cover multiple components or make selective repairs without purchasing excessive material, while the continuous roll format supports both original equipment and aftermarket customization work.
