Fire Sleeve 4AN 12mm ID 6ft Black

The Fire Sleeve 4AN 12mm ID 6ft Black from REDHORSE PERFORMANCE is a heat-resistant sleeve designed to protect braided fuel lines, brake lines, and transmission cooler lines in high-temperature engine bays. This product is ideal for mechanics and automotive enthusiasts who require durability in demanding applications, such as turbocharged setups, modified fuel systems, or vintage restorations.

Constructed with a woven fiberglass exterior, this fire sleeve is designed to shield vulnerable hose runs from radiant engine heat, road debris, and abrasion. It features a 12mm inner diameter that accommodates 4AN hose without restricting flow or creating pressure points. The black synthetic material resists UV degradation and maintains its integrity under thermal cycling, making it suitable for protecting fuel systems near turbos or superchargers.

This sleeve is essential for any fuel system upgrade, forced-induction build, or performance cooling modification where OEM routing passes near hot surfaces. Its compact 6-foot length allows for point-to-point protection in mid-size engine compartments or multiple shorter runs across manifolds and headers, making it a versatile choice for various automotive applications.
