This 1/2" stainless steel bung and plug kit is a shallow-depth weld fitting option for Innovate wideband O2 sensors, suited to stainless piping installations. It provides modest additional clearance while preserving exhaust flow to the sensing element and can help manage sensor heat exposure. A corrosion-resistant alternative where stainless construction is preferred.
