6AN to 1/4NPT EFI Adpt SAE Quick-disconnect

The REDHORSE PERFORMANCE 6AN to 1/4NPT EFI Adapter SAE Quick-Disconnect is a precision fluid-line coupling engineered for high-pressure fuel systems, coolant circuits, and pneumatic applications. This straight-configuration quick-disconnect fitting provides a male 6 AN connection on one end and a female 1/4-inch SAE quick-disconnect port on the other, enabling secure, leak-resistant connections in performance fuel injection systems, air suspension networks, and custom hydraulic setups.

Constructed from aluminum with a black anodized finish, this adapter resists corrosion and oxidation while maintaining a lightweight profile—critical in racing and off-road applications where every ounce matters. The 6 AN male thread size accommodates standard braided hose assemblies, while the SAE quick-disconnect female end allows fast, tool-free coupling and uncoupling without spillage. The straight configuration eliminates bulky elbows in confined engine bays and tight installation spaces, streamlining the overall plumbing layout while preserving flow characteristics.

This fitting serves motorsports builders, fuel system technicians, and performance enthusiasts who demand OEM-grade coupling reliability. It is commonly used in EFI fuel rail systems, turbo boost lines, intercooler circuits, and pneumatic control applications where repeated disconnects and consistent sealing are non-negotiable. The combination of AN and SAE ports addresses mixed-specification systems found in street rods, custom trucks, and race vehicles.

Part of the REDHORSE 881 Series quick-disconnect family, this adapter integrates seamlessly into modular fuel, coolant, and air systems. Weighing only 0.07 pounds with compact dimensions, it minimizes installation weight and footprint. Each unit is sold individually, allowing builders to assemble custom multi-connection manifolds or repair failed couplings in existing systems.
