10AN to 8AN(1/2)NPT Adapter 45

The REDHORSE PERFORMANCE 10AN to 8AN (1/2) NPT Adapter 45 Degree is a precision hydraulic and fuel system fitting designed for high-performance automotive, marine, and industrial applications where reliable fluid transfer is critical. This 45-degree adapter connects 10 AN male ports to 1/2 inch NPT male threads, making it an essential component for custom fuel lines, coolant circuits, and pressurized systems that demand secure, leak-free connections.

Constructed from aluminum and finished in black anodized coating, this fitting provides corrosion resistance suitable for engine bays, marine environments, and systems exposed to moisture and temperature cycling. The 45-degree angle design accommodates tight clearances and unconventional plumbing layouts common in engine swaps, turbo installations, and custom fuel system builds. The AN (Army-Navy) 10 connection standard ensures compatibility with industry-standard -10 hose and fittings, while the NPT (National Pipe Thread) side accepts standard pipe-threaded components and adapters, offering flexibility in mixed-standard plumbing scenarios.

This adapter is ideal for fabricators, performance builders, and technicians constructing custom fuel systems, coolant bypasses, and auxiliary circuits on modified vehicles. It solves the common problem of connecting AN-standard hose systems to existing NPT-threaded ports without requiring multiple adapters or compromises on system routing. Whether integrating a new fuel pump, turbocharger supply line, or remote filter mount into an older platform with NPT infrastructure, this fitting provides a direct, compact solution.

REDHORSE PERFORMANCE is recognized in the performance automotive community for precision aluminum fittings that meet rigorous pressure and vibration standards. The 823 series represents their standard-duty adapter line, balancing strength with weight for motorsports and street applications. Weighing just 0.1 lbs, this compact fitting integrates seamlessly into confined engine bay layouts without adding complexity to the plumbing architecture.
