AN Weld Bung 6AN Male Steel

The AN Weld Bung 6AN Male Steel from ALLSTAR PERFORMANCE is a precision-engineered weld-on fitting designed for high-pressure fuel and fluid systems in performance racing and automotive applications. This 6AN male bung serves as a closed-end port terminator or mounting point in custom fuel line configurations where a sealed, welded connection is required. Used extensively by fabricators and racers building custom fuel systems, oil coolers, and turbo manifolds, this component ensures system integrity under extreme pressure and temperature conditions.

Machined from steel and finished in natural (unplated) form, the AN Weld Bung 6AN Male Steel provides a robust weld surface for permanent installation into manifolds, tanks, and custom chassis components. The 6AN male thread standard (equivalent to -6 JIC) accepts standard 6AN hose adapters and fittings, enabling compatibility with industry-standard fuel and fluid lines rated for high-flow applications. The weld-on design eliminates threaded port complications in custom fabrication, allowing the bung to be securely welded directly into steel substrates for vibration-resistant, leak-free performance even in motorsport environments subject to extreme G-forces and thermal cycling.

This fitting is ideal for custom fuel system builders, race car fabricators, and performance engine builders who require permanent, high-reliability port solutions on fuel tanks, catch cans, radiators, and manifolds. Installation requires welding equipment and basic fabrication skills; proper positioning and penetration are essential for system safety. The natural steel finish allows the bung to integrate seamlessly into welded assemblies and can be painted or coated to match system aesthetics. Lightweight at 0.08 lbs, it contributes minimal weight while delivering the strength required for professional-grade racing and street performance applications.
