304 Stainless Steel O2 Sensor Bung

Our O2 sensor bung allows for a seamless entry point to install your O2 sensor on your exhaust system. These use a standard M18 thread; standard for all automotive and marine applications. Some powersports and motorcycle applications will use a smaller M12 thread instead.

Whether it be on your exhaust manifold, headers, or down-pipe, the sensor bung will withstand high exhaust temperatures, and is corrosion-resistant.
