1.12in ID Firesleeve 3'

The 1.12in ID Firesleeve 3' by Aeroquip is a premium thermal protection solution engineered for high-performance automotive and motorsports applications where fuel lines, brake lines, and hoses face extreme heat exposure. Whether you're running a modified engine bay with aggressive turbo or supercharger setups, building a race car, or protecting critical fuel system components near headers and exhaust manifolds, this firesleeve delivers reliable insulation where stock routing simply won't suffice. Mechanics and enthusiasts trust Aeroquip's reputation for quality—this product is designed to prevent fuel vaporization, brake fluid degradation, and hose failure in environments that routinely exceed 300°F.

Constructed from high-temperature fiberglass material, the 1.12-inch inner diameter sleeve provides a snug fit around AN hoses and fuel lines within that size range, creating an air gap that reflects radiant heat away from the line itself. The 3-foot length offers flexibility for routing through engine bays of various configurations, allowing you to protect the most vulnerable sections of your fuel and coolant systems. Aeroquip's firesleeve construction is proven to reduce line surface temperatures by 100–150°F compared to unprotected hoses running in the same thermal environment, significantly extending component lifespan and reducing the risk of pressure loss or catastrophic failure during competition or spirited driving.

This firesleeve is ideal for fabricators, engine builders, and weekend warriors who demand reliability in modified powertrains. It pairs perfectly with braided stainless steel fuel lines and adapters, integrating seamlessly into custom fuel system builds, LS engine swaps, and turbo installations where headers run close to fuel rails. Installation is straightforward—simply slip the sleeve over your hose before final routing—and the lightweight design (1.95 lbs) adds negligible mass. Ensure your line's outer diameter matches the 1.12-inch inner diameter specification for a secure fit; the 3-foot length can be cut to length if needed. For serious builders refusing to compromise on fuel system integrity under heat, Aeroquip's Firesleeve is an essential component.
