Stainless Bros M18x1.5 O2 Sensor Bung 1.75in to 2.50in Tubing

This is an M18x1.5 O2 sensor bung from Stainless Bros, designed to be welded onto exhaust tubing between 1.75 inches and 2.50 inches in diameter. It provides a threaded port for installing an oxygen sensor into a custom exhaust system. If you're fabricating a new exhaust or modifying an existing one, this bung gives you a solid place to mount your O2 sensor.

Made from stainless steel, this bung is built to withstand the heat and corrosive environment of an exhaust system. The M18x1.5 thread size is standard for most modern O2 sensors, making it a versatile choice for many applications. You'll need to weld this part into place, so ensure you have the proper welding equipment and skills, or have a professional do the installation for you.
