Ledaut M18X1.5 Bung and Plug Notched Style Stepped Notched Style Mounting Bung and Plugs (1 Bungs/1 Plugs)

Sizing was perfect for what I needed, decent quality and no complaints.

I used these for my 98 Mustang Gt. Worked perfectly.

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....

Perfect for a 28mm exhaust!

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

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!

did its job

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