What size threads does this O2 bung plug have?

This plug features M18 x 1-1/2" threads, which is a common size for many O2 sensor bungs. It's always a good idea to verify your bung's thread size before purchasing.

What material is the O2 bung plug made from?

The plug is CNC machined from 303 stainless steel. This material is chosen for its resistance to corrosion and high temperatures commonly found in exhaust systems.

Should I use anything when installing this plug?

Yes, Stainless Works recommends using an anti-seize compound on the threads when installing the plug. This will help prevent the plug from seizing into the bung over time, making it easier to remove later.

About this part

Product Details

This is a hex head plug from Stainless Works, designed to seal off an O2 sensor bung when you're not running a sensor. It's made from 303 stainless steel, which holds up well in exhaust environments. The CNC machining ensures a clean finish and a good fit for your bung.

The plug has M18 x 1-1/2" threads and a 1-1/8" outer diameter, with a 3/4" hex head for easy installation or removal using a socket. It's a straightforward way to cap off a bung, whether you're temporarily removing a sensor or preparing for a tune. Stainless Works recommends using anti-seize compound on the threads when you install it to make sure it comes out easily later.
