AN to NPT 45 Degree #6 x 3/8

The Triple X Race Components AN to NPT 45 Degree #6 x 3/8 adapter is a crucial fitting designed for high-performance fuel and fluid systems in custom automotive builds. This compact adapter bridges two industry-standard thread standards—AN (Army-Navy) and NPT (National Pipe Thread)—making it essential for applications such as fuel injection tuning and hydraulic brake upgrades. Its 45-degree configuration allows for tight routing in confined engine bays while ensuring leak-free pressure integrity.

Machined from aluminum with a black anodized finish, this adapter is built to resist corrosion and maintain durability under sustained fuel pressure and temperature cycling. The #6 AN port has a 3/8-inch outer diameter, which is compatible with various fuel systems. The compact dimensions (1.95 x 0.85 x 2.85 inches) and minimal weight (0.04 lbs) make it ideal for weight-conscious racing applications where every ounce matters.

This adapter is particularly beneficial for experienced mechanics and fabricators who are retrofitting carbureted engines with modern fuel injection systems or upgrading from mechanical to electronic boost control. Its design ensures compatibility across a range of OEM and aftermarket fuel systems, making it a versatile choice for custom-plumbing dual-carb fuel rails and other performance applications.
