M18X1.5 Bung and Plug Notched Style (2 Bungs/ 2 Plugs) Notched Style Fitting Bungs M18X1.5

Finally a product that is worth its weight in gold, it seems that nothing you buy actually fits the component its suppost to work with and yet these simple little bungs can be so hard for a shop to make the curvature to fit its workpiece...anyhow this company got the arc just right and fits like a glove, great quality and im happy with it. This may seem trivial, but even though this item is somewhat self explainatory i still feel there should be some kind of direction(s) as how to impliment this task. But what do i know....

I gave it 5 stars in everything because it doesnt leak, threads were good, and I welded it so it was bound to be perfect 😂 on a serious note I'm a welder by trade and had no issue after cleaning the protective oils off rigging them to the exhaust I built for my truck.

These o2 sensor bungs are ideal for welding into aftermarket exhaust to give you somewhere to mount an o2 sensor. Just drill a hole and weld these on. Be sure to use a little anti-sieze on the plugs if you use those.

These worked well, the angle is meant for a very narrow pipe, maybe 1.5" diameter pipe. Still welded (MIG) just fine on my 2" steel pipe. I would leave the plug in so you don't get crap in the threads.

Nice quality and just what I needed, I would recommend to anyone in need of O2 sensor applications.

Exactly what I needed after shearing the old bung off the exhaust pipe. I’m not exactly someone who knows what they’re doing with a welder, but it worked out well!

Didnt fit my 3in exhaust had to grind to make it fit

had to shape a little for a 3" down pipe with my angle grinder but no biggie! also just weld a little at a time so you don't fry it!
