AN Weld Bung 16AN Female Aluminum

The ALLSTAR PERFORMANCE AN Weld Bung 16AN Female Aluminum is a precision-engineered weld-on fitting designed for high-performance fuel and fluid system applications. This 16 AN female O-ring bung provides a secure, leak-free connection point in custom fuel line installations, transmission coolers, and hydraulic system builds where permanent welded attachment is required. The aluminum construction and natural finish deliver corrosion resistance suitable for marine, racing, and off-road environments where reliability under pressure is non-negotiable.

The 16AN female O-ring design accepts industry-standard 16AN male hose fittings and adapters, creating a repeatable seal across multiple connections. The weld-on construction eliminates the risk of vibration-induced loosening that can occur with threaded bosses, making it ideal for high-vibration applications in racing engines, turbo systems, and off-road vehicles. Aluminum construction keeps weight minimal while maintaining structural integrity under operating pressure, a critical consideration in performance build specifications where every pound matters. The O-ring face seal ensures compatibility with standard AN hose and fitting assemblies used throughout the racing and custom automotive industry.

This bung serves builders and technicians fabricating custom fuel delivery systems, upgrading cooling systems, or installing auxiliary hydraulic circuits. It is commonly used in engine bay modifications where OEM fuel or coolant ports are inadequate for performance upgrades. The weld-on mounting method requires professional fabrication but provides superior vibration isolation compared to threaded inserts. Buyers should confirm tank or component material compatibility before welding and ensure proper surface preparation for optimal bond strength.

AN (Army-Navy) standard fittings remain the industry baseline for motorsports fuel systems, aircraft hydraulics, and custom performance plumbing. The 16AN size accommodates moderate-to-high flow rates while maintaining compact dimensions for space-constrained engine bays. This bung is sold individually, allowing builders to configure custom port patterns across fuel tanks, oil coolers, and transmission systems without purchasing full kits or unnecessary quantities.
