3/8 Male to 6an ORB OE Quick Connect Fitting

The 3/8 Male to 6AN ORB OE Quick Connect Fitting by EARLS is a precision fuel line adapter designed for builders and mechanics upgrading fuel delivery systems on performance vehicles. This 90-degree angle fitting bridges a 3/8 inch SAE male quick disconnect port to a 6 AN (AN6) ORB (O-Ring Boss) threaded inlet, enabling seamless integration between OE fuel supply lines and modern aftermarket fuel system components. It's essential for custom fuel rail installations, fuel pressure regulator plumbing, and any application where space constraints or routing angles require a compact directional transition.

Engineered from stainless steel and aluminum with black anodized finish, this fitting delivers durability and corrosion resistance critical for fuel system reliability. The ORB (O-Ring Boss) connection on the 6AN side employs a captured sealing ring, eliminating the need for tape or sealant and reducing leak risk under fuel system pressure cycles. The SAE quick disconnect male end allows for tool-free separation, streamlining both initial installation and future maintenance—a feature valued in race and street-performance applications where quick-connect convenience matters. The compact 1.5 x 0.9 x 2.9 inch footprint and minimal 0.07 lbs weight make it ideal for tight engine bays where clearance around fuel rails, injector bungs, or pressure regulators is limited.

This adapter is most commonly used in turbocharged and naturally aspirated EFI swaps, fuel system upgrades, and aftermarket fuel rail configurations where OE quick-disconnect supply lines connect to modern AN-threaded components. The 90-degree angle is particularly valuable when fuel lines must change direction to avoid collision with intake manifolds, engine bay obstacles, or hoses. Installers should verify that both the 3/8 SAE male quick disconnect and the 6AN ORB port are present on their fuel supply line and destination component—correct sizing prevents leaks and fuel odor. Installation is straightforward: insert the SAE quick disconnect into the supply line port until it clicks, then thread the 6AN ORB end firmly into the target inlet using appropriate wrench sizing.
