#6 Male Weld Bung Aluminum

The #6 Male Weld Bung Aluminum from FRAGOLA is a precision-engineered fitting designed for welding into custom fuel system, cooling system, and hydraulic line applications. This weld-on bung accepts #6 AN (Army-Navy) male connectors and serves as a permanent mounting point for fluid transfer lines in high-performance automotive, racing, and industrial hydraulic systems. Its aluminum construction offers excellent strength-to-weight ratio, making it an ideal choice for fabricators and engine builders who demand reliability in custom plumbing setups.

This weld bung features a 1-inch stepped design that provides a robust welding base for secure fusion to tank walls, manifolds, or custom chassis components. The male AN thread configuration ensures compatibility with industry-standard #6 AN hose fittings and adapters, creating leak-free connections under pressure. Aluminum material is favored for its corrosion resistance in fuel and coolant environments, reduced thermal conductivity, and ease of machining for custom installations. The weld-on construction eliminates the need for threaded bosses or mechanical fasteners, allowing direct integration into virtually any tank or line configuration.

Professionals in custom fabrication, race car construction, and hot rod restoration rely on FRAGOLA weld bungs to create permanent, pressure-rated connection points without compromise. This component is essential for builders constructing fuel surge tanks, overflow reservoirs, or custom coolant distribution systems where welding offers superior structural integrity compared to bolt-on alternatives. Installation requires standard TIG or MIG welding equipment and proper surface preparation; the finished assembly can be pressurized and tested immediately after cooling. Compatible with all #6 AN male threaded hose ends, adapters, and gauge fittings.
