The Endura Carb. Fitting #6 to 5/8-20 is a precision adapter designed for high-pressure hydraulic and fuel system applications where reliable connections are non-negotiable. This straight fitting bridges two different port standards—an AN6 male thread and a 5/8-20 male thread—making it essential for custom fuel lines, carbureted engine builds, and performance plumbing projects. Whether you're assembling a classic hot rod fuel system, upgrading a vintage carburetor setup, or fabricating a motorsports hydraulic circuit, this adapter provides the secure, leak-free transition your system demands.
Manufactured by Russell, a trusted name in fluid handling solutions, this fitting is constructed from aluminum and finished with nickel anodization for corrosion resistance and durability under vibration and temperature cycling. The nickel-anodized surface protects against oxidation while maintaining excellent wettability for proper sealing with AN-spec hose and tubing. The straight configuration eliminates flow restriction and simplifies installation in tight engine compartments, while the precision machining ensures consistent thread engagement and eliminates cross-threading issues. Its compact profile (2.7 x 1.65 x 4.8 inches) and lightweight design (0.06 lbs) make it ideal for weight-conscious builds without sacrificing strength.
This fitting is ideal for fabricators, engine builders, and motorsports enthusiasts who require OEM-grade reliability in custom applications. It pairs seamlessly with AN6 hose assemblies and carburetor inlet fittings that use 5/8-20 threads, making it a critical link in fuel delivery systems for street rods, muscle cars, and race engines. Installation is straightforward: apply thread sealant to the 5/8-20 male end if connecting to a threaded port, or use a compatible female fitting on the AN6 side with properly assembled AN hose. Always verify port sizes and thread pitches before ordering to ensure compatibility with your specific carburetor or fuel system component.
