Stainless Bros M18x1.5 O2 Sensor Bung Saddle Type

Stainless Bros is known for making parts for custom builds and fabrication projects. This M18x1.5 O2 sensor bung is a saddle-type piece, meaning it's designed to be welded onto a curved surface, like an exhaust pipe. It gives you a clean, threaded port to install an oxygen sensor in a custom exhaust system or anywhere else you need one.

This bung is made from stainless steel, which holds up well to exhaust heat and won't rust out. The M18x1.5 thread size is standard for most modern oxygen sensors, making it a versatile choice for many projects. You'll need to weld this part into place, so make sure you have the right equipment and skills, or plan to have a shop do it for you.
