Oxygen Sensor Bung

Description

Walker Products Oxygen Sensor Bungs are precision-manufactured OE Replacement components designed to provide a secure, leak-free mounting location for threaded oxygen sensors in automotive exhaust systems. Each bung is engineered to match OE thread pitch, diameter, and material characteristics, ensuring full compatibility with upstream or downstream O2 sensors. Constructed from high-strength, corrosion-resistant steel, these bungs withstand extreme exhaust temperatures, road salt, and vibration. Whether used in exhaust system repairs, custom fabrication, or sensor relocation, Walker O2 Sensor Bungs ensure that the sensor is positioned properly within the exhaust stream—allowing accurate air-fuel ratio readings and emissions system performance. These bungs are suitable for weld-in or replacement applications and support a wide range of sensor types used in gasoline and diesel engines. Trusted by technicians and fabricators, Walker Oxygen Sensor Bungs help maintain emissions compliance, support engine control accuracy, and extend the life of installed sensors.
