#10 to #8 O-Ring Male Adapter Fitting

The #10 to #8 O-Ring Male Adapter Fitting is a precision AN line adapter engineered for fuel system applications where size or configuration changes are required. Manufactured by MAGNAFUEL/MAGNAFLOW FUEL SYSTEMS, this adapter bridges two different AN male ports, enabling seamless integration in custom fuel distribution setups, carbureted engines, and EFI fuel systems. Technicians and engine builders rely on these adapters to maintain consistent flow paths while reducing connection points that could compromise system integrity.

Constructed from aluminum and finished in purple anodized coating, this straight-through adapter features O-ring seals at both the #10 AN male and #8 AN male ports, ensuring leak-free operation under pressure. The O-ring design eliminates the need for thread sealant tape, providing a more reliable hydraulic seal that resists fuel degradation and thermal cycling. The adapter's compact footprint—measuring 3.05 x 1 x 3.8 inches and weighing just 0.06 lbs—makes it ideal for tight engine bay installations where space is at a premium, while the purple anodized finish provides both corrosion resistance and easy identification in complex fuel systems.

This adapter is essential for custom fuel system builders, racing teams, and restoration shops working with modular fuel line configurations. Whether stepping down from a larger #10 AN line to a smaller #8 AN connection or adapting aftermarket fuel rails and regulators, this fitting ensures consistent AN-spec performance across all ports. Installation is straightforward—simply hand-tighten until the O-ring seats, then apply one-quarter turn with a wrench to lock the connection. Compatible with all industry-standard AN hoses and fittings, the #10 to #8 O-Ring Male Adapter Fitting is the professional choice for leak-free, reliable fuel delivery.
