M18X1.5 Bung and Plug Notched Style (4 Bungs/ 4 Plugs) M18X1.5

Needed to attach our O2 sensor to the dirt bike exhaust pipes for testing on our dyno. We welded these into our test pipes and when you want to actually test ride our tunes on the track we just screw in the plug.They were delivered quick at a fair price!

Get the hot glue gun out. It works as expected. Dont forget to run a tap through and use never seize

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....

Easy to weld and they have great threads

Needed to shave the the radius to match smaller diameter tubing, but the weld-ability is great, welded nicely and very nice quality.

The bung and the plug look good. Haven’t used the parts yet.

Mount good use bolt instead of plug and have a tape before welding. After welding with plug I had issues with threads

Going to install my first air-fuel gauge and needed to mount the oxygen sensor. Installed both bungs. My gauge only has 1 sensor but wanted to be able to move it side to side to tune the carb. Once the carb is set I plan to plug the other side. These came with the plugs so I can move the sensor and gauge to another car either on a temporary or permanent basis.
