Flare Caps; Size: -6 AN

The Flare Caps; Size: -6 AN from VIBRANT PERFORMANCE is an essential fitting component for high-performance fuel and fluid systems in modified vehicles. These caps serve as protective closures for AN (Army-Navy) hose fittings, preventing contamination, fluid leakage, and air ingress when lines are disconnected or capped off. Whether you're building a custom fuel system, upgrading to braided stainless steel hoses, or working on a turbo cooling circuit, flare caps maintain system integrity and cleanliness during assembly, storage, and operation.

Engineered for reliability, the -6 AN flare cap features a precision-machined aluminum construction designed to seal securely against standard AN flare fittings without galling or cross-threading. The -6 AN designation indicates a nominal 3/8-inch hose diameter, making this size ideal for fuel feed lines, return lines, and coolant circuits in street performance and race applications. VIBRANT PERFORMANCE's attention to detail ensures consistent thread engagement and a gas-tight seal, critical when pressurized systems or volatile fluids are involved. The lightweight design adds negligible weight to your system while the corrosion-resistant finish protects against fuel degradation and thermal cycling stress.

Professional mechanics and enthusiasts rely on these flare caps during fuel system overhauls, turbo upgrades, and custom plumbing modifications on turbocharged, supercharged, and naturally aspirated builds. Installation is straightforward—simply hand-thread onto the male AN flare fitting until snug, then use an appropriate wrench for final tightening if needed. Compatible with all standard -6 AN fittings and hose assemblies, these caps are essential spares for any serious fabricator's toolkit and ideal for protecting open lines during extended storage or system troubleshooting.
