Aluminum Weld Bung -16AN Female

The Vibrant Performance Aluminum Weld Bung -16AN Female (VIB11165) is a precision-engineered weld-on fitting designed for high-flow hydraulic and fuel system applications in performance vehicles, racing engines, and custom fuel delivery systems. This aluminum component provides a secure, weldable junction point for -16AN female connections in fuel lines, cooling circuits, and turbo supply applications where direct welding to the system is preferred over threaded mounting.

Constructed from lightweight aluminum with a natural finish, this 16AN female bung features a 1-5/8-inch outside diameter (OD) weld flange—a standard bore that accommodates -16AN hose or tubing with consistent flow characteristics. The weld-on design eliminates fitting rotation and potential leak points inherent in threaded connections, making it ideal for systems subjected to vibration, thermal cycling, or high-pressure transients common in supercharged and turbocharged engines. The aluminum construction keeps system weight minimal while maintaining structural integrity at rated pressures.

This bung is essential for custom fuel system builders, race car fabricators, and performance shops installing aftermarket fuel systems, aux cooling lines, or turbo feed and return circuits. Users in drag racing, road racing, and street performance applications rely on weld-on bungs to eliminate vibration-induced loosening and ensure lasting system integrity under sustained boost pressure and high engine temperatures. The -16AN female port allows direct connection to standard fuel line adapters and hose ends without additional reducers.

Vibrant Performance is recognized for producing OEM-quality hydraulic and fuel system components trusted across the tuning and motorsports community. This weld bung carries the precision tolerances and material standards expected for critical fuel system junctions, ensuring reliable long-term performance in demanding powerplant environments.
