Aluminum Weld Bung -10AN Female

The Aluminum Weld Bung -10AN Female from Vibrant Performance is a precision-engineered welding fitting designed for custom fuel system, coolant line, and fluid transfer applications in performance vehicles and specialty automotive builds. This weld-on bung serves as a port termination point or connection hub, allowing fabricators and technicians to integrate -10 AN (JIC) lines into fuel tanks, manifolds, and custom plumbing without relying on threaded bosses. Built for serious enthusiasts who demand reliability in high-heat and high-pressure environments, this aluminum bung is ideal for drag racing, street performance, and custom hot rod construction.

Constructed from durable aluminum, this weld bung features a 1-1/8 inch outer diameter (OD) and a female -10AN port, enabling direct connection to -10AN male fittings and hose adapters. The weld-on design provides superior strength and vibration resistance compared to threaded alternatives, ensuring a permanent, leak-free seal when properly welded to steel or aluminum substrates. Vibrant Performance's precision manufacturing guarantees dimensional accuracy and thread integrity, critical when integrating custom fuel delivery or cooling systems. The natural aluminum finish is compatible with most welding processes and accepts paint or protective coating post-installation, making it suitable for both hidden tank applications and visible engine bay setups.

This fitting is indispensable for fabricators building custom fuel tanks, turbo cooling circuits, and aftermarket fuel system conversions on muscle cars, imports, and off-road vehicles. Installation requires welding expertise and proper surface preparation to ensure full-strength joints; TIG or MIG welding is recommended for aluminum-to-aluminum or aluminum-to-steel bonds. The -10AN female port accommodates standard automotive AN hose and fitting sizes, ensuring compatibility with most performance fuel system components and aftermarket filtration assemblies. Weighing just 0.03 lbs, it adds minimal mass while delivering the structural integrity required in competitive and street-driven applications.
