#16 Male Weld Bung

The #16 Male Weld Bung from FRAGOLA is a precision-engineered aluminum fitting designed for high-performance fuel system and hydraulic line applications. This weld-on bung accommodates 16 AN (fluid power) connections and serves technicians, fabricators, and performance enthusiasts who require reliable, custom hose routing in modified fuel systems, race engines, and hydraulic assemblies. The weld-on design allows permanent integration into custom fuel cells, tanks, and manifold blocks where leak-free performance is non-negotiable.

Constructed from lightweight aluminum in natural finish, the #16 Male Weld Bung features a 1-inch step transition that ensures flush, secure mounting when welded directly to tank walls or custom fabricated structures. The 16 AN male thread specification matches industry-standard hose adapters and fittings, enabling seamless integration with FRAGOLA hose assemblies and competing AN-threaded components. This weld-on construction eliminates the need for threaded ports, making it ideal for tanks and manifolds where internal threading is impractical or impossible.

Ideal for drag racers, off-road builders, and custom fabricators, the #16 Male Weld Bung integrates seamlessly into fuel cell builds, remote-mounted fuel systems, and custom hydraulic circuits. Professional installers and DIY enthusiasts rely on FRAGOLA fittings for their reputation in high-vibration and high-temperature environments. Proper TIG or MIG welding technique is required during installation to ensure structural integrity and fuel-system safety compliance.
