18mm Mild Steel Oxygen Sensor Bung

Add a secure mounting point to your exhaust system with this universal oxygen sensor bung designed for standard M18 x 1.5 threaded O2 sensors. Ideal for custom exhaust fabrication, wideband O2 sensor installations, or adding additional monitoring ports, this bung provides a reliable solution for proper sensor placement.

Constructed from durable mild steel, it is easy to weld and forms a strong, leak-resistant connection once installed. The integrated internal lip helps prevent the bung from protruding too far into the exhaust tubing, supporting proper sensor positioning and consistent exhaust flow. Sold individually, this weld-in bung is a practical addition for custom GM and Chevy exhaust setups or other applications requiring an M18 x 1.5 oxygen sensor mounting point.
