AN to NPT Straight #8 x 3/8

The TRIPLE X RACE COMPONENTS AN to NPT Straight #8 x 3/8 adapter is a precision hydraulic and pneumatic fitting designed to bridge AN (Army-Navy) and NPT (National Pipe Thread) port configurations in high-performance applications. This aluminum adapter features black anodized finish for corrosion resistance and is engineered for systems where AN8 male connections must interface with 3/8-inch NPT male ports—a common requirement in custom fuel systems, brake lines, and cooling circuits on race engines and performance vehicles.

Constructed from aerospace-grade aluminum and anodized for durability, this straight adapter maintains the integrity of sealed hydraulic and pneumatic systems. The black anodized surface resists oxidation in moisture-prone environments and provides a professional appearance in engine bay installations. AN8 male threading on one end delivers secure engagement with -8 hose fittings and component ports, while the 3/8-inch NPT male port on the opposite end threads directly into NPT-threaded manifolds, blocks, and adapters. The compact 2.7 x 0.95 x 3.15-inch profile and 0.04-pound weight minimize system complexity and weight penalty—critical factors in motorsports and lightweight builds where every ounce impacts performance.

This adapter serves race teams, custom fabricators, and enthusiasts who require reliable port conversion in fuel injection systems, transmission coolers, radiator circuits, and turbo feed lines. Compatibility across AN and NPT thread standards eliminates the need for multiple adapters and reduces potential leak points. The straight configuration—as opposed to 45-degree or 90-degree elbows—simplifies hose routing in tight engine compartments and maintains direct flow paths. TRIPLE X RACE COMPONENTS specializes in precision motorsports fittings, and this adapter meets the exacting standards expected in competitive racing and high-reliability build specifications.
