Inverted Flare Adapter Fitting -6AN to 1/2in-20

The Inverted Flare Adapter Fitting -6AN to 1/2in-20 by Vibrant Performance is an essential component for building high-flow fuel and fluid systems in custom automotive projects. This precision adapter connects AN (Army-Navy) line standards to NPT (National Pipe Thread) connections, facilitating the integration of modern fuel injection systems and turbo supply lines into vehicles with mismatched factory fittings.

Manufactured from aerospace-grade aluminum, this fitting is designed to withstand the pressures of fuel systems and resist corrosion from ethanol blends. The -6AN port accommodates standard 3/8-inch hose with AN crimped fittings, while the 1/2-inch NPT 20 TPI female end threads directly into engine blocks, fuel rails, or manifold ports without the need for additional adapters. Its compact design (3.54 × 0.75 × 6.3 inches) is ideal for tight engine bays.

This adapter is particularly beneficial for mechanics and engine builders looking to convert carbureted engines to EFI, install high-capacity fuel pumps, or set up custom turbocharger systems. With its lightweight construction at just 0.02 pounds, it adds minimal weight to your fuel system plumbing while ensuring reliable performance.
