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 an essential hydraulic fitting for high-performance engine builds, fuel system conversions, and custom plumbing applications. This 45-degree adapter bridges 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. Whether you're upgrading a carburetor fuel line, installing remote oil coolers, or routing hydraulic lines in a race engine bay, this adapter eliminates the need for costly custom hose fabrication.

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 (1/2-inch outer diameter), while the 3/8-inch NPT side threads directly into factory or aftermarket NPT ports—no sealant tape required due to NPT's tapered thread design. Triple X Race Components manufactures this adapter to strict OEM standards, ensuring leak-free seals under sustained pressure and vibration-prone engine bay environments.

This fitting suits 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 favor this adapter for its compact 1.95-inch length and minimal weight (0.05 lbs), critical when managing wiring and hose routing in tight engine compartments. Installation is straightforward: thread into the NPT port with appropriate thread sealant (PTFE tape or liquid sealant recommended for NPT), then connect your AN-sized braided hose via the reusable AN fitting—a five-minute upgrade that eliminates guesswork in plumbing design.
