AN to NPT 45 Degree #8 x 3/8

The AN to NPT 45 Degree #8 x 3/8 adapter from Triple X Race Components is a crucial hydraulic fitting designed for high-performance engine builds, fuel system conversions, and custom plumbing applications. This 45-degree adapter seamlessly connects two industry-standard thread types—AN (Army-Navy) and NPT (National Pipe Thread)—allowing builders to integrate modern braided hose systems with legacy or specialized NPT-threaded components.

Engineered to precise tolerances, the AN to NPT 45 Degree #8 x 3/8 features a 45-degree exit angle that optimizes space-constrained installations while reducing turbulence in fuel and coolant delivery. The #8 AN side accepts standard -8 braided hose (5/8-inch outer diameter), while the 3/8-inch NPT side threads directly into factory or aftermarket NPT ports. While NPT's tapered thread design can create a seal, using sealant tape is often recommended to ensure a leak-free connection.

This fitting is ideal for bracket-style fuel systems, gravity-fed cooling loops, and vintage engine swaps where NPT ports are standard but modern braided hose offers superior reliability. Mechanics and engine builders appreciate this adapter for its compact length of 1.95 inches and minimal weight, making it a practical choice for various automotive applications.
