Filler Bung

If you're looking to add an o2 sensor, petcock drain, or plumbing fitting to automotive components like exhaust tubing, oil pans, fuel cells, or intake manifolds, then a quality weld-in bung is a smart choice. Weld-in bungs are not only essential for custom exhausts, but they can also save you time and hassle when adding fittings to oil pans or fuel cells. Additionally, weld-in bungs are useful for those building custom nitrous systems. At Pit Stop USA, we offer a variety of weld-in bungs in different sizes and threads, including aluminum and steel options and AN, metric, and NPT threads. Find the perfect weld-in bung for your automotive component needs at Pit Stop USA.

Filler Bungs are used with Filler Plug Kits that include a weld-in bung and an easy grip O-ring cap with positive seal. Kits are often used as an inspection plug or a filler plug.
