AN Weld Bung 8AN Female Aluminum

The AN Weld Bung 8AN Female Aluminum from Allstar Performance is a precision-engineered weld-on fitting designed for high-performance fuel and fluid systems in race engines, custom hot rods, and competition vehicles. This 8 AN female O-ring port weld bung provides a permanent, leak-free connection point for fuel lines, coolant circuits, or breather systems where a flush-mounted, welded installation is required.

Constructed from lightweight aluminum, this weld bung is engineered to withstand the pressure and temperature cycles common in performance applications while minimizing weight penalties. The 8 AN female port accepts standard -8 AN hose fittings and incorporates an O-ring seal for dependable fluid containment. The weld-on design allows fabricators to integrate the fitting directly into custom manifolds, tanks, and intake systems, eliminating the need for threaded bosses or adapters and creating a streamlined, integrated fuel or cooling circuit. The natural aluminum finish resists corrosion in typical automotive environments and accepts anodizing or coating for enhanced durability in salt-air or corrosive conditions.

This fitting is ideal for engine builders, fabricators, and motorsports enthusiasts constructing fuel injection systems, fuel cell adapters, oil cooling circuits, or custom coolant bypass ports. The weld-on configuration ensures a structurally sound, pressure-rated connection that does not depend on mechanical fasteners or thread engagement, making it a preferred choice for systems operating under sustained high fuel pressure or thermal stress. Engineers and builders select Allstar Performance weld bungs for applications ranging from circle-track racing and drag racing to street-performance builds where reliability and clean integration are non-negotiable.
