Aluminum Weld Bung -6AN Male

The Vibrant Performance Aluminum Weld Bung -6AN Male (VIB11151) is a precision weld-on port fitting designed for custom fluid line routing in high-performance fuel, coolant, and hydraulic systems. This aluminum bung accommodates -6AN (3/8-inch) male AN connections and features a robust flange footprint engineered to distribute loads evenly across welded joints, making it essential for fabricators building race-spec fuel systems and custom cooling loops.

Constructed from lightweight aluminum in a natural finish, this weld-on fitting delivers material efficiency without sacrificing structural integrity. The flange provides adequate surface area for TIG or MIG welding, ensuring the bung integrates securely into aluminum or steel manifolds and tanks. The -6AN male thread allows direct coupling to standard AN hose fittings.

This fitting serves fabricators, engine builders, and custom system integrators who demand precise port connections on non-standard manifolds, catch tanks, surge tanks, and cooler mounts. Vibrant Performance is recognized for producing OEM-quality AN fittings and adapters used throughout the performance aftermarket, and this bung reflects that manufacturing standard.
