About Stainless Bros O2 / Sensor Bung

Stainless Bros O2 and sensor bungs provide weld-in threaded mounting points for oxygen sensors and other exhaust instrumentation. The tubing diameter or saddle shape determines how the bung sits on the pipe, while thread size must match the sensor exactly. Angled versions can help position the sensor body away from surrounding components or improve access. Confirm both the sensor thread and the tubing diameter before welding the bung into the system.

Fabrication Note: Confirm material grade, tubing size, wall thickness, connection style and all listed dimensions before cutting or welding. Custom-fabrication components are generally not vehicle-specific unless an exact engine, turbocharger or sensor application is stated in the product details.
