Steel Weld Bung -6AN Male

The Steel Weld Bung -6AN Male from Vibrant Performance is a precision-engineered fuel system component designed for custom fuel system fabrication and high-performance engine builds. This weld-on bung accommodates -6 AN (1/2-inch nominal) fuel line systems and serves as a permanent mounting point for fuel injection rails, carburetor inlets, or auxiliary fuel distribution lines. Fabricators, engine builders, and performance enthusiasts rely on this fitting to create clean, integrated fuel system architectures without relying on bulky threaded fittings or external adapters.

Constructed from steel with a natural finish, the Steel Weld Bung features a 7/8-inch flange that provides ample surface area for secure TIG or MIG welding directly onto fuel tank walls, intake manifolds, or custom fuel system brackets. The male -6AN port accepts standard AN hose fittings and adapters, ensuring compatibility with any -6AN fuel system component. Steel construction offers superior durability and thermal stability compared to aluminum alternatives, making it ideal for high-heat engine compartment environments and fuel systems subject to pressure cycling or vibration.

This component is essential for fabricators building custom fuel systems, turbo kits, fuel cell installations, and race car plumbing where permanent, leak-free connections are non-negotiable. The weld-on design eliminates future leaks at threaded connection points while reducing system complexity. Proper MIG or TIG welding technique and joint preparation are required for installation; ensure adequate cooling time and pressure testing after fabrication to verify system integrity.
