AN to NPT 45 Degree #12 x 1/2

The AN to NPT 45 Degree #12 x 1/2 adapter is a precision hydraulic and pneumatic fitting designed for high-performance racing and industrial fluid transfer systems. Built by Triple X Race Components, this male-to-male adapter bridges two common thread standards—12 AN (Army Navy) on one end and 1/2 inch NPT (National Pipe Thread) on the other—in a compact 45-degree angled configuration. Engineers and technicians rely on this fitting to route fuel lines, coolant hoses, and brake fluid systems in tight engine bays where straight connections would create routing conflicts or clearance issues.

Machined from aluminum and finished in black anodized coating, this adapter combines lightweight strength with corrosion resistance—critical properties in motorsports environments where vibration, temperature swings, and exposure to harsh fluids demand durability. The 45-degree angle reduces the overall footprint of fluid distribution assemblies while the NPT male thread (tapered design) creates a mechanical seal against NPT female ports without requiring additional sealant tape in most applications. The #12 AN size accommodates larger flow rates than smaller fittings, making it suitable for primary cooling circuits and fuel delivery systems in race-prepped vehicles and custom hydraulic installations.

This adapter serves professional engine builders, race teams, and custom vehicle fabricators who need reliable cross-standard connections without sacrificing space or performance. Its lightweight aluminum construction (0.12 lbs) makes it ideal for weight-conscious builds, while the anodized finish protects against oxidation in underhood environments. Installation requires only standard wrenches or hose fittings; ensure NPT threads are clean and consider using thread sealant tape on NPT connections for maximum leak prevention in high-pressure systems.
