AN Weld Bung 6AN Male Aluminum

The AN Weld Bung 6AN Male Aluminum from ALLSTAR PERFORMANCE is a precision-engineered port closure fitting designed for high-performance fuel and fluid systems. This weld-on bung serves as a permanent sealing solution for AN-ported components in racing engines, custom fuel systems, and hydraulic applications where thread-on fittings are impractical. Available for sale, it delivers reliable port management in demanding motorsports and automotive fabrication environments.

Constructed from aluminum in natural finish, this 6AN male weld bung features a robust welded-joint design that creates a permanent, vibration-resistant connection ideal for high-pressure fuel systems and engine bay installations. The 6AN port size (3/8-24 thread specification) matches industry-standard AN fittings, ensuring compatibility across most custom fuel systems and hydraulic builds. Its lightweight aluminum construction minimizes added mass while maintaining structural integrity under pressure cycling and thermal cycling common in race applications.

Fabricators, engine builders, and automotive technicians rely on this weld bung to seal unused AN ports during system assembly and modifications. Installation requires TIG or MIG welding to an aluminum or steel component, making it ideal for custom fuel cell construction, turbo installations, and modified fuel distribution systems. Mechanics and racers frequently purchase this specification when converting between fuel line configurations or permanently closing ports in carbureted-to-fuel-injection conversions and aftermarket engine builds.
