The 6AN Flare Cap Nut 2 Piece Black by REDHORSE PERFORMANCE is an essential component for custom fuel, coolant, and hydraulic systems in high-performance vehicles, engine swaps, and race builds. These cap nuts seal AN fittings with a reliable flare connection, preventing leaks in pressurized circuits where precision engineering matters.
Designed for 6AN hose and tubing assemblies, this flare cap nut uses a 37-degree flare cone geometry that mates precisely with standard AN fittings, creating a metal-to-metal seal that withstands fuel system pressures, coolant flow, and hydraulic load cycles. The black finish resists corrosion and oxidation in engine bay environments while offering a clean, professional appearance in custom installations.
Two-piece construction ensures you have backup hardware on hand, critical when working on time-sensitive builds or maintenance jobs where a single failed fitting can sideline your vehicle. This cap nut suits fuel injector conversions, LS engine swaps, custom radiator hose transitions, and any modular powertrain upgrade requiring leak-proof connections.
