AN to NPT 45 Degree #3 x 1/8

The AN to NPT 45 Degree #3 x 1/8 adapter from Triple X Race Components is a precision hydraulic and fluid line fitting designed for high-performance automotive, motorsports, and industrial applications. This adapter serves as a critical junction point in custom fuel systems, brake lines, and coolant circuits where AN (Army-Navy) fittings on one component must connect to NPT (National Pipe Thread) ports on another. Engineers and fabricators rely on these adapters to ensure leak-free connections in demanding environments where pressure consistency and reliability are non-negotiable.

Constructed from aluminum and finished in black anodizing, this fitting combines lightweight durability with corrosion resistance—essential properties for engine bays and exposed installations. The 45-degree configuration allows flexible line routing around tight spaces and complex engine layouts without kinking or flow obstruction. The #3 AN male thread (0.375-inch diameter with -3 sizing) connects to the 1/8-inch NPT male port, enabling seamless integration between AN hose assemblies and NPT-threaded components. The anodized finish not only protects against oxidation and UV degradation but also provides a professional appearance that withstands thermal cycling and vibration common in race and street applications.

This adapter is ideal for custom fuel system builds, turbo installations, transmission coolers, and any application requiring robust cross-thread compatibility. Fabricators, hot rodders, and OEM engineers benefit from the compact 3.05-inch length and lightweight 0.02-pound design, which minimize installation footprint while maintaining structural integrity under pressure cycling. Proper sealing requires compatible hose and thread sealant; ensure all connections are torqued to specification and inspected regularly in high-vibration environments to maintain system integrity and safety.
