-6AN Female to 5/16in Tu be Adapter Fittings

The -6AN Female to 5/16in Tube Adapter Fitting by VIBRANT PERFORMANCE is a precision hydraulic and pneumatic connector designed for fuel systems, coolant lines, and pressurized fluid transfer in high-performance automotive, motorsports, and industrial applications. This adapter bridges the gap between AN (Army-Navy) port standards and metric tubing sizes, making it essential for custom fuel system builds, engine conversions, and aftermarket modifications where component integration requires compatible fitting solutions.

Manufactured from aerospace-grade aluminum with black anodized finish for corrosion resistance and durability, this straight-end fitting incorporates a brass ferrule seat that creates a leak-free seal under high pressure and temperature cycling. The -6AN female port accepts standard AN hose ends, while the 5/16-inch tubing connection accommodates metric or standard barrier tubing, providing flexibility in system design. The anodized aluminum construction resists oxidation and maintains structural integrity in fuel, oil, and coolant environments, while the compact design (3.45 x 0.8 x 3.55 inches, 0.05 lbs) ensures space-efficient installation in tight engine bays.

Performance enthusiasts, engine builders, and system integrators benefit most from this adapter when converting between legacy tubing networks and modern AN-standard components. Installation requires standard tubing tools and basic mechanical knowledge; the straight configuration allows axial hose routing without bends, reducing pressure drops and simplifying routing around obstacles. Ensure tubing inside diameter matches 5/16-inch specifications and that the brass ferrule is properly seated during assembly to prevent leaks under operating pressure.
