The Stainless Bros M18x1.5 O2 sensor saddle-type bung is a stainless fitting that clamps onto existing tubing to provide a threaded M18x1.5 port for an oxygen sensor. It’s useful when adding a sensor to an exhaust run without cutting and welding a full boss, enabling easier sensor placement during fabrication or retrofits.
