AN to NPT 90 Degree #4 x 1/8

The AN to NPT 90 Degree #4 x 1/8 adapter from Triple X Race Components is a precision hydraulic fitting specifically designed for fuel system applications in automotive and racing contexts. This adapter bridges two critical industry standards—AN (Army-Navy) and NPT (National Pipe Thread)—allowing seamless integration between components that use different thread specifications.

Constructed with precision engineering, the AN to NPT 90 Degree #4 x 1/8 features a compact right-angle design that saves space in tight engine bays where parallel runs aren't feasible. The #4 AN port accommodates standard -4 hose sizes (1/4-inch outer diameter), while the 1/8-inch NPT port integrates with common pressure sensors, bypass valves, and auxiliary fuel system components. Triple X Race Components manufactures these adapters to exacting tolerances, utilizing materials and thread sealing techniques that withstand fuel system pressures and temperature fluctuations typical in racing and modified street vehicles.

This adapter is ideal for fuel system builders, performance mechanics, and enthusiasts fabricating custom fuel delivery setups. The 90-degree orientation is essential when routing fuel lines around engine blocks, turbochargers, or intercoolers where straight adapters create installation conflicts, ensuring leak-free connections under demanding conditions.
