-6 Welding Bung 9/16

The -6 Welding Bung 9/16 from XRP-XTREME RACING PROD. is a purpose-built aluminum weld-on port designed for custom fuel system, coolant line, and hydraulic applications in high-performance automotive builds. This fitting serves as a sealed mounting point for carbureted engines, fuel injection systems, and closed-loop cooling circuits where reliability and vibration resistance are non-negotiable. Whether you're fabricating a custom fuel cell, integrating braided hose lines, or building a competition engine bay, this weld-on bung provides a structurally integral connection point that won't loosen under harsh track conditions or extreme heat cycles.

Engineered as a female O-ring port with a 6 AN thread size, this aluminum bung accepts -6 AN hose fittings and delivers a leak-free seal through dual O-ring geometry that accommodates thermal expansion and vibration without degradation. The weld-on design eliminates threaded boss reliance, allowing fabricators to position ports at custom angles and locations on tanks, manifolds, and custom brackets. Natural aluminum finish resists corrosion in typical automotive environments while remaining light enough to support weight-reduction builds. The compact 2.7 x 1.15 x 4 inch footprint and 0.08 lb weight make integration seamless into tight engine compartments and custom fuel cell designs.

Street rodders, circle track racers, and professional fabricators rely on this weld-on bung for fuel cell construction, custom radiator bypass lines, and turbo coolant return systems where stock port locations don't align with custom layouts. TIG or MIG welding onto aluminum, steel, or stainless steel substrates ensures permanent, vibration-proof attachment that outlasts threaded connections in motorsports duty. For anyone building or modifying fuel delivery, cooling, or hydraulic systems where port reliability directly impacts performance and safety, the -6 Welding Bung 9/16 delivers the structural integrity and seal quality demanded by serious engine builders.
