-6AN Male to 5/16in Tube Adapter Fitting

The VIBRANT PERFORMANCE -6AN Male to 5/16in Tube Adapter Fitting is a crucial component for custom fuel, coolant, and brake line systems in performance and street-modified vehicles. This adapter effectively connects AN (Army-Navy) threaded fittings with standard 5/16-inch tubing, making it essential for builders transitioning between different plumbing standards or integrating aftermarket fuel systems, turbo cooling lines, or custom brake setups.

Manufactured by VIBRANT PERFORMANCE, this -6AN to 5/16-inch adapter features a robust design that ensures leak-free operation under pressure. The -6AN male thread (0.865-14 UNF) interfaces seamlessly with standard 5/16-inch diameter tubing, accommodating both compression and push-on tube styles depending on your system design. The engineering focuses on tight tolerances and material consistency, preventing issues that can arise during installation or thermal cycling.

This adapter is ideal for fuel system builders, turbo cooling system fabricators, and custom brake line designers. Its compact body diameter of 0.8 inches and lightweight construction allow for easy integration into tight engine bays without adding unnecessary bulk. Whether upgrading a classic car's fuel delivery system or fabricating custom cooling circuits on a modern engine swap, this fitting provides the reliable connection point your build demands.
