AN To NPT 90 Degree -12 x 1/2in

The AN to NPT 90 Degree -12 x 1/2in adapter from ALLSTAR PERFORMANCE is a precision hose fitting designed for fluid transfer systems in high-performance automotive applications. This adapter bridges two industry-standard thread types—AN (Army-Navy) and NPT (National Pipe Thread)—allowing mechanics and fabricators to connect components with different port configurations seamlessly.

Built to OEM specification standards, the AN to NPT 90 Degree adapter features a robust aluminum alloy construction that resists corrosion and maintains structural integrity under pressure cycling. The -12 size designation corresponds to a 3/4-inch nominal ID, accommodating moderate to high flow rates typical in performance cooling and fuel delivery systems, while the 1/2-inch NPT port allows integration with metric or SAE-threaded components.

This fitting benefits engine builders, fabricators, and serious enthusiasts who demand reliability in custom or upgraded cooling, fuel, and hydraulic systems. The precision-machined 90-degree elbow geometry directs flow at a right angle, critical for installations where space constraints or plumbing geometry demand directional changes without dead zones that trap air or debris.
