AN Weld Bung 10AN Male Aluminum

The AN Weld Bung 10AN Male Aluminum by ALLSTAR PERFORMANCE is a precision-engineered weld fitting designed for high-performance fuel, oil, and coolant line systems in custom automotive builds. This component serves as a sealed termination point in AN-style plumbing networks, making it ideal for capping off unused ports on aluminum manifolds, tanks, or custom-fabricated fuel rails.

Manufactured from lightweight aluminum alloy and rated for 10AN specifications, this weld bung is engineered to mate seamlessly with 10AN male hose fittings and hard-line connectors used throughout motorsport and street-performance applications. The aluminum construction ensures minimal system weight while maintaining structural integrity under pressure cycles and temperature fluctuations.

Enthusiasts and professional engine builders rely on this fitting for fuel system upgrades, dry-sump conversions, and custom coolant routing in turbo builds where reliability and flow are critical. The welding design allows for permanent integration into custom fabricated tanks, manifolds, or intake runners, creating a unified assembly that reduces joint failure points common with threaded connections exposed to vibration and thermal cycling.
