Male -6AN Male to 5/16in Hose Barb Fitting

The Male -6AN Male to 5/16in Hose Barb Fitting (SKU: VIB11211) is a precision hydraulic and fuel system adapter designed for users who need reliable connections between AN (Army-Navy) threaded fittings and barbed hose connections. This straight adapter serves motorsports enthusiasts, off-road builders, and hydraulic system technicians who require secure, leak-free transitions in custom fuel lines, brake systems, and pressurized fluid applications. The fitting's dual-port design bridges the gap between high-pressure AN standards and flexible hose installation, making it essential for fabricating compatible fluid delivery systems.

Constructed from aluminum and finished with black anodizing, this adapter combines lightweight durability with corrosion resistance—critical properties for both engine bay and marine environments. The -6AN male thread (7/8"-20 SAE standard) mates cleanly with AN-spec component ports, while the 5/16-inch barb inlet accommodates flexible hose with crimped or clamp-secured connections. Black anodized aluminum reduces weight without sacrificing strength, and the straight configuration minimizes flow restriction and turbulence compared to 90-degree alternatives. The compact footprint and 0.03 lbs weight make it ideal for space-constrained installations in performance vehicles and custom hydraulic builds.

This fitting is best suited for custom fuel system routing, aftermarket brake line fabrication, nitrous oxide distribution systems, and pressurized fluid applications in racing and off-road environments. Installation requires the hose to be cut cleanly to length, then slipped over the 5/16-inch barb and secured with a hose clamp or mechanical crimp fitting—no additional adapters needed. Builders working with modular fuel injection setups, custom coolant systems, or hydraulic clutch conversions will find this adapter indispensable for achieving factory-equivalent pressure ratings with user-defined routing. Always verify hose pressure ratings exceed your system's operating pressure for optimal safety and longevity.
