-12AN Male Aluminum Weld Bung (6061-T6)

Engineered for high-flow performance fluid and breather systems, our -12AN male aluminum weld bung is precision CNC-machined from raw, weld-ready 6061-T6 billet aluminum. Featuring a standard 37° sealing flare and 1-1/16"-12 threads, this weld-on fitting creates a leak-free connection capable of handling high-pressure applications. Designed with a stepped pilot shoulder, it aligns cleanly onto custom valve covers, oil pans, catch cans, fuel cells, and radiator tanks for easy TIG welding. Fully compatible with E85, race gas, engine oil, and coolant.
