Tank Weld Bung 1.5in OD Black

The Tank Weld Bung 1.5in OD Black from VIBRANT PERFORMANCE is a premium welded bung and cap assembly designed for fuel cells, catch cans, and aftermarket fuel system installations. This component provides a secure, sealed opening in cylindrical tanks where a 1.5-inch diameter hole exists. Tank bungs are essential for systems requiring periodic access or expansion relief while maintaining fuel system integrity and safety during high-performance driving conditions.

Constructed from aluminum with black anodized finish, this weld-on bung features a threaded aluminum cap that seals reliably against fuel vapors and spillage. The 1.5-inch outer diameter sizing accommodates standard 1.5-inch opening specifications common in aftermarket fuel system components. Black anodizing provides corrosion resistance and a finished appearance that resists oxidation in fuel environments, while the threaded cap design allows quick hand-access without tools. The weld-on construction ensures permanent structural integrity—once properly welded by a qualified technician, the bung becomes a single unified component with the tank.

This bung kit benefits builders, fabricators, and performance enthusiasts constructing or upgrading custom fuel systems, catch cans, and auxiliary tanks. Installation requires welding—a certified welder should perform the installation to ensure a fuel-tight seal and structural safety. Compatible with any fabricated tank featuring a 1.5-inch diameter opening, the Tank Weld Bung 1.5in OD Black delivers the reliability and durability expected from a recognized manufacturer in the performance fuel systems market.
