#16 Male Weld Bung w/1.5 Dia Step

The #16 Male Weld Bung w/1.5 Dia Step from FRAGOLA is a precision-engineered hydraulic and fuel line fitting designed for welded installation in high-performance applications. This aluminum weld-on bung accommodates #16 AN (Army-Navy) male connections and is built for systems requiring permanent, leak-free integration into custom fabrication projects. Whether you're building competition racing fuel systems, hydraulic brake lines, or custom fluid transfer networks, this bung provides the structural integrity and compatibility that professional technicians and fabricators demand.

The weld-on design eliminates threaded connection points, reducing potential leak paths and simplifying integration into tank walls, fuel rails, or custom manifolds. The 1.5-inch diameter step provides a precisely machined bearing surface that ensures proper fitment when welded, while the natural aluminum finish resists corrosion in most fluid environments. FRAGOLA's engineering ensures this #16 Male Weld Bung meets AN specifications for thread pitch and connection geometry, making it fully compatible with standard #16 AN hose fittings and hard-line adapters used throughout motorsports, aerospace, and industrial hydraulic systems.

Installation requires TIG or MIG welding to secure the bung flush against the mounting surface—a permanent solution preferred by fabricators who prioritize reliability over removable fittings. This product is ideal for fuel cell installations, custom fuel system builds, and hydraulic line integration where vibration, thermal cycling, and high pressure demand absolute connection security. Lightweight at 0.1 lbs and compact in profile, the bung fits seamlessly into tight engine bay or chassis configurations. Verify wall thickness and material compatibility with your welding equipment and substrate before installation to ensure optimal fusion and system performance.
