AN To NPT 45 Degree -6 x 1/2in

The AN to NPT 45 Degree -6 x 1/2in adapter from ALLSTAR PERFORMANCE is a precision-engineered fitting designed for high-pressure fluid transfer systems in performance engines, fuel injection setups, and hydraulic circuits. This adapter bridges the gap between AN (Army-Navy) and NPT (National Pipe Thread) connections, allowing seamless integration of components with different threading standards. Whether you're building a custom fuel system, upgrading coolant lines, or integrating aftermarket hydraulic components, this 45-degree elbow fitting delivers the directional flexibility and reliability that professionals demand.

Constructed from aerospace-grade aluminum and finished with black anodized coating for corrosion resistance, the AN to NPT 45 Degree adapter combines durability with lightweight performance. The 45-degree offset geometry reduces stress on adjoining hoses and fittings by redirecting flow at an optimal angle, rather than forcing sharp 90-degree bends that can restrict flow or cause fatigue failure. The -6 AN (3/8-inch diameter) to 1/2-inch NPT male conversion ensures compatibility with both metric and imperial plumbing standards, making it invaluable for custom engine builds and retrofits where OEM specifications may not align with aftermarket components.

This fitting is essential for fabricators, engine builders, and performance enthusiasts working on fuel systems, oil cooler lines, and transmission cooling circuits where vibration isolation and precise angle routing are critical. The black anodized finish resists corrosion in underhood and external environments, while the aluminum construction keeps overall weight minimal—ideal for race and street applications. Installation requires standard AN and NPT wrenches; thread sealant is recommended for NPT connections to ensure a leak-free seal under pressure.
