Stainless Bros O2 Sensor Bung Motorcycle SS304 M12x1.25 50.8mm Tubing

If you're fabricating a custom exhaust system for your motorcycle and need to add a port for an oxygen sensor, this bung from Stainless Bros is what you'll need. It's designed to be welded onto tubing with a 50.8mm (2-inch) outer diameter, providing a secure mounting point for an M12x1.25 O2 sensor.

This bung is made from SS304 stainless steel, which is a well-known material for its resistance to corrosion and heat, making it a solid choice for exhaust components. The M12x1.25 thread size is common for many motorcycle O2 sensors, ensuring compatibility when you're ready to install your sensor. You'll need to weld this part into place, so make sure you have the proper welding equipment and skills, or plan to have a professional do the installation for you.
