6AN Bulkhead Adapter 90 Male Male Black

The 6AN Bulkhead Adapter 90 Male Male Black from REDHORSE PERFORMANCE is a precision-engineered fluid line fitting designed for custom fuel system, coolant, and hydraulic applications in performance and street vehicles. This adapter solves a critical plumbing challenge: joining two male 6AN fittings at a 90-degree angle where space constraints or routing geometry demand an offset connection. Whether you're fabricating a custom fuel cell setup, re-plumbing a turbo cooling circuit, or adapting aftermarket fuel injector rails, this compact adapter delivers the reliability that separates professional builds from amateur work.

Constructed from anodized aluminum with a black finish, the 6AN Bulkhead Adapter features a robust 90-degree elbow configuration with male inlet and outlet ports on both ends. The bulkhead design allows the fitting to pass through engine bay firewall or chassis mounting points, reducing clutter and creating a cleaner appearance while maintaining full flow capacity. At just 0.08 lbs and measuring 2.8 x 1.1 x 3.75 inches, it occupies minimal real estate in tight engine bays while the aluminum construction resists corrosion and vibration fatigue common in high-performance applications. The precision SAE thread tolerances ensure leak-free connections when paired with proper 6AN hose crimp fittings and application of thread sealant.

This adapter is essential for custom fabricators, engine builders, and motorsport technicians routing fuel systems in LS swaps, small-block conversions, and turbo builds where OEM geometry doesn't match modern fuel delivery standards. It integrates seamlessly with any 6AN hose and fitting combination, whether you're using braided stainless steel or rubber hose with crimp or reusable fittings. Installation requires only standard wrenches and the same meticulous attention to torque specs and thread prep that separates reliable high-pressure systems from catastrophic fuel leaks. Verify your system's pressure rating and hose sizing before ordering—this adapter handles fuel, coolant, and hydraulic circuits across the automotive performance spectrum.
