Wasn't sure these would work to plug the outlet holes in my British Berkefeld Water Filter... as I lost the original plugs. But these work perfectly... nice and tight and water doesn't leak through. Also I have extras for future projects. Received within a couple days.

This is good quality. I made something using it making a hole in the center and it is very stronghold but not too steep.

Easily blocks paint from drilled holes that aren't to be painted. Used for masking Primed but not painted holes in machined parts.

I used these in my outdoor birdbath after my husband drilled a hole for a quick drain for me. I was using organic cork, but they kept rotting away. This provided an excellent barrier for the water to stay in the birdbath! Great idea - they also look cute in my old fashioned bottles for a pop of color!

Silicone stoppers (bungs) last longer than rubber and the price was comparable to the rubber bung.I love that they are long and the size was perfect for the larger test tubes
