Product Description

By entering your model number, you can make sure that this fits.
The 304 stainless steel O2 oxygen sensor mounting bung was made in a notched style and was easy to weld.
The oxygen sensor plugs were made from zinc-plated mild steel.
Our oxygen sensor plugs are M18 x 1 in. in size. All standard O2 sensors are compatible with the 5 thread.
Weld bung and plugs were simple to put together and provided excellent value for money.
Designed to add an 02 sensor to any location that requires one. Great for installing custom exhaust systems, headers, and down pipes, among other things.

Questions & Answers

Will they fit a 3" pipe because of the radius cut?

It won't matter if the radius cut isn't perfect because you'll be able to fill in the gaps.

Hello, I'm looking for bungs that will fit Bosch LS01 lambdas. Are you two on the same page? The diameter appears to be closer to 16 inches. ?

It was perfect for my needs.

Will this keep one of the o2 sensor holes sealed off if I buy an aftermarket downpipe for my car with two o2 sensor holes?

To seal the bungs, they must be welded to the pipe all the way around. You'll need to have your pipes/bungs TIG welded if they're stainless steel.

The fit is perfect, and the quality is excellent
5/5

Finally, a product that is worth its weight in gold; it appears that nothing you buy actually fits the component it is supposed to work with, and yet these simple little bungs can be incredibly difficult for a shop to make the curvature fit its workpiece. Anyway, this company got the arc just right and it fits like a glove, it's of great quality, and I'm pleased with it. This may seem insignificant, but even though this item is self-explanatory, I believe there should be some sort of direction(s) as to how to complete this task. But, hey, I'm not an expert.

What more can you ask for than a good weld that doesn't leak? I gave it five stars in every category because it doesn't leak, the threads are good, and I welded it myself, so it had to be perfect
5/5

On a serious note, I'm a welder by trade and had no trouble rigging them to the exhaust I built for my truck after cleaning the protective oils off.

Your bunghole will benefit from bungs
5/5

These o2 sensor bungs are designed to be welded into aftermarket exhaust to provide a mounting location for an o2 sensor. Simply drill a hole and affix these to it with welding. If you're going to use anti-bacterial soap, make sure to use some anti-bacterial soap as well. If you're using plugs, keep a tight grip on them.

These worked well, the angle is meant for a very narrow pipe, maybe 1
5/5

These were a good value, the radius was a little tight for most exhaust. I welded (MIG) just fine on my 2" steel pipe with a 5" diameter pipe, but I would leave the plug in to keep the threads clean.

It works! After shearing the old bung off the exhaust pipe, this was exactly what I needed; I'm not exactly a welder expert, but it worked out well!

It didn't fit my 3in exhaust pipe, and I had to grind it down to get it to fit

perfect!
5/5

With my angle grinder, I had to shape a little for a 3" down pipe, but it was no big deal! Also, only weld a small amount at a time to avoid frying it!.
