AN to NPT Straight #8 x 3/8

The TRIPLE X RACE COMPONENTS AN to NPT Straight #8 x 3/8 adapter is designed for mechanics and fabricators working on high-performance engine builds and fuel system modifications. This fitting bridges the gap between AN (Army-Navy) and NPT (National Pipe Thread) standards, making it essential for integrating aftermarket fuel delivery systems, brake lines, and pressurized components.

Purpose-built for applications such as drag racing and complex engine swaps, this adapter eliminates the need for custom fabrication when connecting different port types. The straight configuration allows for direct flow, minimizing turbulence and pressure drops in fuel rails, nitrous systems, and brake proportioning valves. A #8 AN port connects to a 3/8-inch NPT male thread, facilitating seamless integration between modern braided stainless AN hose assemblies and legacy NPT fittings.

Engine builders and experienced fabricators trust this adapter for plumbing custom fuel systems, installing aftermarket fuel pressure regulators, or retrofitting modern fuel injection onto classic engines. Manufactured to precision tolerances, it ensures leak-free operation under the high pressures typical in turbocharged and supercharged applications. Its compact design and lightweight construction make it a reliable choice for any performance application.
