Fire Sleeve 3/4in x 25ft

The Fire Sleeve 3/4in x 25ft from DESIGN ENGINEERING is a professional-grade hose and wire protection system engineered for serious automotive builders and mechanics who demand heat shielding in high-temperature engine bays. Whether you're running turbo lines near exhaust manifolds, fuel lines through the engine compartment, or electrical harnesses in close proximity to headers, this fire sleeve provides critical thermal protection that prevents melting, degradation, and potential safety hazards. Mechanics and performance enthusiasts rely on this product to extend the service life of fuel injection systems, brake lines, and wiring while maintaining clean, organized installations.

Constructed from a durable silicone and fiberglass composite, the Fire Sleeve 3/4in x 25ft delivers superior heat resistance and durability compared to standard plastic or rubber sleeves. The 3/4-inch inner diameter accommodates most hose and wire bundle configurations common in modern and classic vehicles, while the full 25-foot length provides sufficient coverage for comprehensive engine compartment protection on a single roll. Included 16 inches of fire tape ensures secure, professional wrapping and sealing at termination points, preventing fraying and maintaining consistent insulation integrity even under vibration and thermal cycling. The black exterior blends seamlessly with engine bay aesthetics while resisting UV degradation and fluid contamination.

This fire sleeve is essential for turbo builds, LS engine swaps, fuel system upgrades, and any custom automotive project where hoses or wiring route through zones exceeding 200°F. Professional shops, weekend warriors, and restoration specialists benefit from the reliability and repeatability of DESIGN ENGINEERING's proven thermal protection. Installation is straightforward—simply wrap the sleeve around target hoses or harnesses and secure with the included fire tape for a finished, secure installation. Compatible with most aftermarket fuel lines, power steering hoses, and wire harnesses; verify 3/4-inch diameter clearance before ordering to ensure proper fit within your engine compartment layout.
