Bungs, Weld-On Fittings & Threaded Bosses

Bungs and weld-on fittings are threaded bosses that get welded to exhaust pipes, intake tubing, oil pans, headers, and fabrication projects to provide a mounting point for sensors, fittings, plugs, and accessories. The right bung ensures a clean, leak-free sensor or fitting mount on any custom fabrication.

OneFastShop carries bungs including stainless steel and mild steel weld-on bungs, O2 sensor bungs, EGT probe bungs, oil drain bungs, NPT and AN threaded bungs, bung plugs, and assorted sizes for exhaust, turbo, cooling, and oil system fabrication projects.

Every bung at OneFastShop ships brand-new and ready to weld. Whether you're adding an O2 sensor location to a custom exhaust, welding a drain plug to an oil pan, or mounting a temperature probe on a turbo manifold, OneFastShop has the right bung. Shop the full bungs collection today.
