Aluminum Weld Bung 1/2in Female

The Aluminum Weld Bung 1/2in Female is a precision-engineered welding component designed for fluid transfer and hydraulic system applications where durability and corrosion resistance are critical. This weld-on bung features a 1/2-inch NPT female threaded port, allowing secure connection to hoses, fittings, and instrumentation in demanding industrial and mobile equipment environments. Constructed from aluminum alloy in its natural finish, this component delivers the lightweight advantage essential in aerospace, automotive, and marine fabrication where weight savings matter.

The 1/2-inch NPT female thread accommodates standard industrial hose connections and allows for flush-face or quick-disconnect coupling integration depending on your system design. Aluminum construction provides inherent corrosion resistance compared to steel alternatives, particularly valuable in high-moisture or salt-air environments common in marine equipment, agricultural machinery, and off-road vehicle applications. The weld-on design enables permanent, pressure-rated integration into tank walls, manifold blocks, or custom fabricated assemblies, eliminating the need for separate mounting brackets or additional fasteners. Minimal weight addition—at 0.04 lbs—makes this component ideal for weight-conscious builds where every pound counts.

This bung suits fabricators, welders, and equipment manufacturers who need reliable port solutions for custom tank builds, fuel systems, cooling circuits, and hydraulic manifolds. Whether you're building a recovery vehicle fluid management system, aerospace auxiliary equipment, or agricultural spray equipment, this aluminum welding component provides proven performance in field conditions. The compact 0.85-inch diameter keeps the profile low on finished assemblies while the female thread design accepts standard NPT male fittings or adapter hoses without additional components.
