6AN to 5/16in SAE Quick Disconnect Female STR

The 6AN to 5/16in SAE Quick Disconnect Female STR from REDHORSE PERFORMANCE is a precision fluid coupling adapter designed for high-performance fuel, oil, and coolant systems in custom-built and modified vehicles. This fitting is essential for serious automotive enthusiasts and fabricators, bridging the gap between metric AN sizing (6AN) and standard SAE nomenclature (5/16in). It is particularly useful for engine swaps, turbo installations, and custom fuel system builds.

This straight-thread quick disconnect fitting features a female SAE connection that accepts standard 5/16in male disconnect couplers, allowing for rapid disconnection and reconnection without spillage or system drainage. The 6AN port on the opposite end accommodates metric hose barbs and AN-spec fittings commonly found in modern performance fuel systems and custom plumbing applications. The design is compact and lightweight, making it easy to route in tight engine bays.

Ideal for those converting carbureted engines to fuel injection or adapting aftermarket fuel components, this adapter simplifies connections while maintaining reliability under pressure. REDHORSE PERFORMANCE fittings are manufactured to exacting tolerances, ensuring leak-free operation under various conditions. This product is a must-have for anyone looking to enhance their vehicle's performance and reliability.
