AN To NPT 90 Degree -16 x 3/4in

The AN To NPT 90 Degree -16 x 3/4in adapter from ALLSTAR PERFORMANCE is an essential fluid distribution fitting for high-performance engine builds, fuel systems, and hydraulic line management. This adapter bridges two industry-standard thread protocols—AN (Army-Navy) and NPT (National Pipe Tapered)—allowing seamless integration between components that might otherwise require custom modifications or workarounds. Whether you're fabricating a custom fuel rail, plumbing a cooler circuit, or adapting legacy hydraulic lines to modern AN-spec systems, this 90-degree elbow connector solves compatibility challenges without sacrificing flow integrity or introducing leak points.

The -16 AN port (1 inch diameter fitting) paired with a 3/4-inch NPT male thread creates a robust mechanical junction rated for sustained pressure applications. The 90-degree configuration eliminates sharp bends in your line routing, reducing turbulence and fatigue stress on hose assemblies while freeing up engine bay real estate in cramped installations. ALLSTAR PERFORMANCE's precision manufacturing ensures tight tolerances on both threads, minimizing the need for excessive sealing compound and preventing weeping at the interface. The compact 4.85 x 1.4 x 6.9-inch footprint and lightweight 0.265-pound design make this fitting ideal for weight-conscious builds without compromising structural rigidity or pressure capability.

Street and strip mechanics rely on this adapter when converting carburetor fuel systems to fuel injection, upgrading cooling loops on LS swaps, or fabricating transmission cooler lines in custom chassis work. It's equally valuable for drag racing fuel cell installations and circle-track applications where plumbing flexibility and system reliability directly impact performance and safety. Installation requires standard wrenching tools and compatible AN hose or tubing with proper crimped fittings on the -16 side; apply thread-sealing compound rated for your fluid type (fuel, oil, or coolant) to the NPT side before assembly. Verify your system pressure rating matches the adapter specification before pressurizing to ensure longevity and eliminate downtime.
