The #10 Coupler Fitting Black from MAGNAFUEL/MAGNAFLOW FUEL SYSTEMS is a precision aluminum adapter designed for high-performance fuel system plumbing in race cars, custom builds, and heavy-duty applications. This straight coupler fitting bridges two 10 AN male O-ring connections, providing a leak-free seal critical for fuel delivery systems operating under high pressure. It is essential for builders looking to ensure reliable fuel flow in demanding environments.
Manufactured from lightweight aluminum and finished in black anodizing, the #10 Coupler Fitting Black resists corrosion while maintaining structural integrity in demanding fuel system environments. The O-ring face seal design (ORFS) creates a crush-sealed connection that accommodates vibration and thermal cycling without weeping or failure—essential for motorsports and turbocharged applications where fuel pressure spikes and engine vibration are constant.
This coupler is ideal for builders upgrading fuel systems on supercharged and turbocharged engines, as well as anyone running high-flow fuel pumps and injectors that demand redundant sealing. The compact form factor allows installation in tight engine bays where space is at a premium, while the lightweight design contributes negligibly to overall vehicle mass.
