The XRP-XTREME RACING PROD. #4 Flare Cap Black is a precision hydraulic fitting cap designed for high-performance fuel and coolant systems in modified and race-built vehicles. Built by XRP, a brand trusted by professional mechanics and motorsports enthusiasts, this flare cap seals AN-spec fittings reliably under extreme pressure and temperature cycling.
Constructed from aircraft-grade aluminum with a durable black anodized finish, the #4 Flare Cap Black resists corrosion and blends seamlessly into modern engine bays. The #4 size threads onto standard AN connectors with precision engineering that ensures a leak-free seal without over-torquing. This cap is essential during long-term storage and protects open fittings during engine work.
Engine builders, fuel system specialists, and performance mechanics reach for XRP flare caps when finishing professional-grade hydraulic assemblies. The lightweight design—just 0.04 lbs—adds no burden to your build while the compact profile fits snugly in tight engine bay configurations typical of street rods and custom motorsports platforms.
