AN to NPT Straight #6 x 3/8

The AN to NPT Straight #6 x 3/8 fitting from Triple X Race Components is a precision adapter designed for high-performance fuel, oil, and hydraulic system plumbing in custom and race vehicle builds. This straight-configuration hose end connects AN (Army-Navy) port standards to NPT (National Pipe Thread) system components, making it essential for builders integrating aftermarket fuel injection systems, turbo oil lines, or custom cooling circuits.

Engineered with precision tolerances, this fitting ensures leak-free, vibration-resistant connections at critical pressure points. The #6 AN port is designed for use with standard -6 hose, which typically has a 3/8-inch outer diameter, while the 3/8 NPT inlet threads into female NPT bosses on engines, radiators, or aftermarket manifolds. The straight design minimizes flow restrictions and pressure drops, which is crucial in high-RPM racing applications.

Engine builders, fabricators, and track enthusiasts rely on this fitting for various applications, including carbureted-to-injected conversions and custom cooling or vacuum systems. The black anodized finish resists corrosion, maintaining a clean appearance in engine bays and ensuring durability in demanding environments.
