Female to Male Extender Fitting; Size -10AN

The Female to Male Extender Fitting in -10AN size is an essential component for custom fuel, oil, and coolant line routing in high-performance automotive builds. Whether you're fabricating a custom intake manifold setup, relocating a fuel regulator, or extending hydraulic lines in a heavily modified engine bay, this adapter allows you to bridge gaps between female and male AN connections without sacrificing flow integrity or system reliability. Vibrant Performance's extender fitting is engineered for builders and mechanics who demand precision fitment and leak-free operation under demanding conditions.

This -10AN fitting features a compact machined aluminum body with precisely formed female threads on one end and male threads on the opposite end, enabling seamless connection between incompatible port configurations. The -10AN designation indicates a 5/8-inch SAE port size, designed to handle high-pressure applications common in turbocharged and supercharged engines, fuel injection systems, and aftermarket cooling circuits. The extender's stub-length geometry (3.65 inches overall) minimizes dead volume in sensitive fuel and oil circuits while maintaining structural rigidity, and the lightweight design at 0.065 pounds integrates cleanly into compact engine bay layouts without adding measurable weight penalty to your platform.

Experienced fabricators and professional tuners rely on this adapter when custom plumbing configurations require transitional geometry that off-the-shelf hard lines cannot accommodate. It pairs seamlessly with -10AN braided hose, compression fittings, and other Vibrant Performance components in forced induction fuel systems, remote oil filter mounts, and auxiliary cooling setups. Installation requires only standard AN wrenches and thread-sealant compound; use on any -10AN port application where you need to extend a female connection to a male connection, or vice versa, ensuring pressure-rated integrity across your entire custom fuel and fluid system.
