I'm a little confused by the numbering of the sizes. In my case, the silicone discs were too big to be used as stoppers in bottles for a project I had to complete immediately. Since I had to have something right away, I decided to cut them down to size. It worked pretty well after a little bit of cutting. However, it would be best to order the correct size.
It was the change in temperature that made them cling to my bottles, now I have to figure out how to remove them.
These silicone products are made of great quality and solid construction. However, if you try to fit them into 6gal PET carboys, they don't fit well. The taper is a bit angled causing them to get stuck. If you want them to stick, it is important to make sure there isn't any liquid contact with the neck. What if I had almost lost six? Good night, guys.
Did what it was described to do. When I need it again, I'll buy it again.
Stoppers that work well.
I've found it to work well.
This product was not purchased for use in a lab. In a pool, I bought it as a plug for water lines. There's something wrong with the fit and seal.
