Silicone Stopper, 1 to 6 Sizes Assortment, Pack of 6

I bought these to adapt a manometer for coffee roaster tryer ports. Nice corks in a variety of sizes that should work for all of my roasters.

well, i tried the black stoppers and then i tried the white stoppers and now i've tried the silicone stoppers. and of course the silicone are the most expensive and the best. they have no odor or taste. they have a slight give that makes them easier to form a seal. now what am i going to do with my plain rubber ones.

Stoppers with accurate size descriptions made of silicone. Not much else can be said.

The allow a certain fitting flexibility.

Cheap crummy. Undersized

Needed a plug for the drainage hole in the bottom of a flower pot so that I could fill it with water and grow bamboo. These silicone plugs really squish and expand to fill the space you put them in, so it was a little bit of a trial to find the right size compared with a simple cork plug, but it works for what I needed. If I have a complaint it would be that you can't just buy one, as I don't really need the others.

I got this set to find the sizes I need for my bottles—they are of good food grade quality and now I know the right sizes for all my bottles.
