Polished Alum. Fill Cap w/Alum. Weld Bung 2in

The Polished Alum. Fill Cap w/Alum. Weld Bung 2in from Vibrant Performance is a complete bung and cap kit designed for custom fuel system fabrication and fluid containment applications. This component is essential for fabricators, hot rod builders, and performance enthusiasts who require a professional-grade sealing solution for 2-inch openings. It is particularly useful for building custom fuel cells, coolant reservoirs, or specialty fluid tanks.

Constructed entirely from aluminum, this weld bung assembly provides a leak-proof interface paired with a removable, threaded cap that allows for easy access and servicing. The aluminum material ensures corrosion resistance and contributes to the lightweight performance critical for motorsport and aftermarket applications. The polished finish enhances aesthetic appeal and facilitates easier inspection for contamination and cleanliness, which is vital in high-performance fuel systems.

Fabricators, restoration shops, and dedicated car builders benefit most from this kit, especially those working on custom fuel cells, auxiliary tanks, or non-OEM fluid reservoirs. The weld-on design guarantees permanent structural integrity once installed, while the aluminum threaded cap enables tool-free removal for filling, inspection, or maintenance tasks. This assembly adds minimal weight to your system while maintaining the durability required for continuous automotive use.
