-6AN Male to 7/16-24 Mal e Inverted Flare Fitting

The -6AN Male to 7/16-24 Male Inverted Flare Fitting by VIBRANT PERFORMANCE is a precision hydraulic and fuel line adapter designed for high-performance automotive applications where reliable, leak-free connections are non-negotiable. This straight adapter fitting bridges two different connection standards—the modern -6 AN (Army-Navy) port and the classic 7/16-24 inverted flare thread—making it essential for engine conversions, fuel system upgrades, brake line modifications, and custom cooling circuits. Whether you're building a race engine, restoring a classic vehicle, or retrofitting modern fuel injection onto a vintage platform, this adapter eliminates the need for separate component sourcing.

Constructed from aluminum and finished in black anodized coating, the -6AN Male to 7/16-24 Male Inverted Flare Fitting delivers corrosion resistance and a clean, professional appearance in engine bays. The black anodized surface protects against oxidation and chemical degradation while maintaining a low-profile aesthetic on display engines. The inverted flare design on the 7/16-24 side ensures a mechanically secure bite and seal, critical for pressurized fuel and hydraulic systems where vibration and thermal cycling demand uncompromising integrity. AN fittings use a 37-degree cone seat geometry, a proven standard that outperforms traditional flare connections in both pressure capacity and reusability across multiple assembly cycles.

Experienced fabricators, engine builders, and fuel system technicians rely on this adapter when merging legacy 7/16-24 inverted flare components with modern AN hose and line assemblies. Installation is straightforward: thread the -6AN male end into your AN port or hose barb fitting, and connect the 7/16-24 inverted flare male end to your fuel rail, carburetor inlet, or brake master cylinder outlet. Always use appropriate thread sealant on inverted flare connections and verify torque specifications for your specific application. At just 0.03 lbs, this compact adapter adds negligible weight while solving critical system compatibility challenges in custom builds and engine swaps where off-the-shelf solutions fall short.
