AN To NPT 45 Degree -8 x 3/8in

The AN to NPT 45 Degree -8 x 3/8in adapter from ALLSTAR PERFORMANCE is a precision hydraulic and fuel line fitting designed to connect AN (Army-Navy) male ports to NPT (National Pipe Tapered) male ports at a 45-degree angle. This adapter is essential for custom fuel system builds, hydraulic brake line assemblies, and engine bay plumbing where space constraints or routing requirements demand angled connections. Whether you're restoring a classic hot rod, upgrading a race car fuel system, or installing aftermarket hydraulic components, this fitting provides the leak-free performance that high-performance applications demand.

Constructed from aircraft-grade aluminum with black anodized finish, the AN to NPT 45 Degree -8 x 3/8in adapter resists corrosion while maintaining lightweight properties critical for performance vehicles. The -8 AN designation indicates an 8-AN hose size (1/2-inch outer diameter), while the 3/8-inch NPT thread accommodates standard plumbing and gauge ports found on fuel regulators, carburetors, and manifolds. The 45-degree angle eliminates sharp bends in hose routing, reducing stress concentrations that lead to hose fatigue and leaks under vibration and pressure cycling. Black anodizing provides durable surface protection and a professional finished appearance in engine bays.

This adapter is ideal for fuel system builders, race teams, and enthusiasts who demand reliable thread-to-hose transitions in tight spaces. Compatible with 8-AN hoses and fittings commonly used in EFI fuel systems, carburetor fuel lines, and hydraulic brake setups, it integrates seamlessly into both street and competition builds. Installation requires standard wrenches; apply thread sealant (PTFE tape or liquid sealant) to NPT threads before assembly to ensure pressure-tight seals. The compact 2.1 x 1.05 x 4.05-inch profile fits easily between firewall, engine block, and frame rails where conventional straight fittings would not.
