AN To NPT 90 Degree -10 x 3/8in

The AN to NPT 90 degree -10 x 3/8in adapter from Allstar Performance is a precision fitting designed to bridge two common hydraulic and pneumatic connection standards in high-performance applications. This adapter is essential for builders and technicians who need to transition between AN (Army-Navy) male connections and NPT (National Pipe Thread) male ports. Whether you're assembling a custom fuel system, brake line configuration, or fluid transfer assembly, this 90-degree adapter provides the angular offset required for tight installation spaces where straight connections prove impractical or impossible.

Constructed from aluminum and finished in black anodized coating, this fitting delivers durability and corrosion resistance in demanding environments. The -10 AN male inlet threads onto standard -10 AN bulkhead or hose end fittings, while the 3/8 inch NPT male outlet accommodates NPT-threaded ports found on many pumps, gauges, and manifolds. The 90-degree geometry allows hose and line routing that follows component layouts without requiring excessive tubing bends, reducing stress on hose assemblies and minimizing pressure losses. Anodizing provides protection against oxidation and wear while maintaining a clean, professional appearance in engine bay or frame installations.

This adapter is ideal for hot rod builders, race technicians, and performance engine builders who regularly mix connection standards in fuel delivery, cooling, and brake systems. The compact 4.1-inch length and lightweight 0.11-pound design integrate seamlessly into tight fabrication scenarios without adding measurable weight or bulk. Installation requires only a wrench on both ends—standard hand tools work quickly to seat the fitting securely. Verify NPT port size on your manifold or component before ordering to ensure proper thread compatibility; NPT sizing differs from AN sizing, making careful specification review essential for leak-free assembly.
