Which O2 Bung Is Right for Your Job? When it comes to stainless steel O2 sensor bungs, there are three common types I typically use: lipped, copped, and standard.

We are very excited to offer two new sizes of stainless steel material 1.75” and 3.5” both in sanitary grade 304l.

We are not only a supply company but still a fabrication shop that uses these...
