Fire Sleeve 6AN 15mm ID 6ft Black

The Fire Sleeve 6AN 15mm ID 6ft Black from REDHORSE PERFORMANCE is essential thermal protection for high-performance fuel, oil, and coolant lines in serious engine builds. Whether you're running a turbocharged street car, a drag-strip competitor, or a custom hot rod, this braided heat sleeve guards against radiant engine heat that can degrade hose integrity and fluid viscosity. Mechanics and enthusiasts rely on REDHORSE's fire sleeves to extend hose life and improve reliability under extreme underhood conditions where factory routing places lines too close to manifolds, turbochargers, or intercooler pipes.

This 6-foot length fire sleeve features a 15mm inner diameter (ID) specifically sized for 6AN hose specifications, a standard in custom fuel and coolant applications. The black braided construction provides superior thermal reflection and durability compared to wrap-style alternatives, resisting abrasion from engine bay movement and vibration. The tight weave and premium material composition allow the sleeve to maintain structural integrity even when exposed to sustained high temperatures, preventing fluid degradation and system failures that can occur when unprotected lines experience radiant heat stress of 200°F and beyond.

Installers and engine builders benefit most from this product when retrofitting performance fuel systems, coolant circuits, and pressurized lines in confined engine compartments. The 6ft length accommodates typical routing distances from fuel pumps to carburetors, or from engine blocks to remote oil coolers—common setups in LS swaps, vintage restorations, and turbo conversions. Simply slide the fire sleeve over your existing 6AN hose before installation to add permanent thermal protection without sacrificing line flexibility or access. Pair with quality AN fittings and hose clamps for a professional, reliable fuel or cooling system that runs cooler and lasts longer under competition or daily driver duty.
