Weld Bung 3/4in NPT Female - Aluminum

The JOES Racing Products Weld Bung 3/4in NPT Female - Aluminum is a marine-grade threaded fitting designed for anglers and boaters who demand reliable deck hardware and fuel system integrity. After decades on the water, any serious boater knows that a single failed fitting can mean a ruined day—or worse. This weld bung serves as a sealed port on fuel tanks, water tanks, and custom marine fabrications, preventing leaks and contamination while maintaining structural integrity under vibration and thermal cycling.

Constructed from lightweight aluminum, the 3/4in NPT Female weld bung combines corrosion resistance with minimal weight—critical when every pound matters on a performance vessel. The NPT (National Pipe Thread) female profile accepts standard 3/4in male adapters, creating a proven seal without requiring sealant tape on every replacement. The compact dimensions of 3 x 0.8 x 4.1 inches make it easy to weld into bulkheads, tank tops, or custom manifolds without disrupting your vessel's balance or structural load calculations.

Whether you're upgrading a custom fuel system, installing auxiliary water tanks, or fabricating a new console frame, this aluminum weld bung delivers the thread security and corrosion immunity that saltwater and freshwater environments demand. JOES Racing Products' proven heritage in high-vibration applications means this fitting has already proven itself under conditions far more demanding than a typical boat install.
