AN to NPT 45 Degree #10 x 1/2

The AN to NPT 45 Degree #10 x 1/2 fitting from TRIPLE X RACE COMPONENTS is a precision adapter designed for high-performance fuel, oil, and coolant systems in custom automotive builds. This angled fitting bridges two industry-standard thread standards—AN (Army-Navy) and NPT (National Pipe Thread)—allowing seamless integration between hydraulic and pneumatic components that would otherwise be incompatible.

Built for racers, hot-rodders, and engine builders who demand reliability under pressure, this adapter eliminates the need for expensive custom fabrication or system redesigns. The 45-degree angle facilitates tight packaging in confined engine bays and reduces strain on fuel lines, brake hoses, and transmission cooler connections by directing flow away from critical components. The #10 AN port connects with a 1/2-inch NPT female port, making it ideal for connecting aftermarket fuel pumps, pressure regulators, and remote filter housings to OEM or custom manifolds.

Triple X's black anodized finish resists corrosion and high-temperature cycling, and the compact design (2.35 x 1 x 3.35 inches) fits tight headers and modified engine compartments without requiring additional brackets or adapters. This fitting is essential for carbureted and fuel-injected V8 builds, LS swaps, and turbo applications where custom plumbing is mandatory. Drag racers and road-course competitors benefit from the angled design's ability to reduce line length and eliminate sharp kinks.
