8AN 45Deg Male Adapter to 1/2in NPT Male Black

The 8AN 45 Degree Male Adapter to 1/2in NPT Male Black by REDHORSE PERFORMANCE is an essential hydraulic and fuel line coupling for custom automotive builds, performance upgrades, and professional engine modifications. This adapter bridges two industry-standard thread types—8AN JIC fittings and 1/2-inch NPT ports—making it indispensable when integrating aftermarket fuel systems, turbocharger supply lines, nitrous oxide systems, or custom cooling loops into older vehicles or engine bays with legacy NPT-threaded components. Whether you're fabricating a fuel rail, plumbing a remote oil cooler, or connecting performance fuel cells, this 45-degree adapter eliminates the need for welding or costly custom fabrication.

Manufactured by REDHORSE PERFORMANCE—a trusted name in motorsports plumbing—this adapter features a 45-degree elbow geometry that optimizes hose routing in tight engine compartments while reducing turbulence and pressure loss in high-flow applications. The male 8AN end accepts standard 8AN hose fittings using AN thread specification, while the male 1/2-inch NPT end threads directly into NPT-ported components without additional adapters. The black anodized aluminum or steel construction resists corrosion in harsh underhood environments and provides reliable durability across repeated thermal cycles. The compact 2.8 x 1.15 x 3.8-inch footprint and lightweight 0.085-pound design make installation straightforward in space-constrained applications like engine bay modifications or transmission cooler setups.

This adapter benefits street rodders, drag racers, engine swap specialists, and DIY mechanics performing custom fuel system or cooling upgrades on carbureted engines, LS conversions, and vintage platforms that retain NPT-threaded ports. It is compatible with any 8AN hose and banjo fitting configuration and works seamlessly with REDHORSE stainless steel braided hose, fuel cells with NPT outlet ports, and aftermarket fuel pumps. Installation requires no special tools beyond an adjustable wrench or AN wrench set; always use thread sealant tape or anaerobic sealant on the NPT end to prevent leaks under pressure. Verify your system's fuel type and pressure rating to ensure component compatibility with your specific modification.
