Aluminum Weld Bung -6AN Female

The aluminum weld bung -6AN female is a specialized fuel system component designed for custom fabricators, hot rodders, and high-performance automotive enthusiasts who need a reliable port for fuel line integration. This weld-on bung provides a permanent, structurally sound connection point in fuel tanks, fuel rails, or custom manifolds where AN fittings are required. Its weld-on design ensures leak-free, vibration-resistant performance in demanding engine bay environments.

Machined from lightweight aluminum, this bung features a 7/8-inch outer diameter base optimized for secure TIG or MIG welding to steel or aluminum substrates without warping or failure. The -6AN female port accepts standard -6 AN hose ends and fittings, allowing seamless integration with high-pressure fuel systems operating at competition and street-strip power levels. The natural aluminum finish resists corrosion in typical fuel environments while remaining easy to inspect for proper weld penetration and integrity during assembly.

Professional fuel system builders, race car fabricators, and street performance builders rely on this bung for custom fuel distribution blocks, surge tank ports, and carburetor feed lines. Installation requires welding equipment and basic metalworking skill; proper heat control prevents thread damage in the female AN port. Compatible with all -6 AN braided hose, fittings, and adapters commonly used in fuel, oil, and coolant systems on street, strip, and circle track applications.
