These work great with an airlock on 5 gallon carboys.

I got these by mistake... and an awesome mistake it was. Since they have that hallow inside, it allows the cork to get deeper n the neck and hold better

I have carboys of several different sizes and styles. This stopper allows me to use them efficiently. Pretty handy, I would say.

I should have read the listing better, this won?t fit plastic carboys. I?ve found another use for it though. It is well made, and I think I like this style of bung better than the solid ones.

A good stopper. fits in store bought cider jugs.
A good stopper. fits in 64oz and 128oz store bought cider jugs. Felt a little unsure about the seal after multiple times of putting in the airlock. Poured a little sanitizer into the top and no bubbles so I feel that it will seal after multiple reseatings of the airlock. Seems to be a harder material that will withstand the oxidative stress of sanitizer unlike other stoppers and caps that dry and crack.

Great for 5 gal glass carboy
I have several 5 gallon glass carboys and these stoppers have worked perfectly in them every time. However, I've had a lot of trouble using them with a 6 gallon glass carboy, as the neck is narrower and the stopper hates to slide down and stay in place (wet or dry). 'Sokay, I never liked using that carboy much anyway, and mostly now only use plastic bucket primary and 5 gallon glass secondary. This is a great stopper in my world!

So So Stopper
I feel I get a better seal from a solid stopper.

Much better than regular stoppers
I like these stoppers. As others have pointed out, they need to be dry to fit well, but otherwise, they are much better than the traditional stoppers that behave much worse in terms of staying in the carboy. Unless you go with a carboy cap, these are the stoppers to use.
May 16, 2014
Not that great
Yes, they fit. However like the other reviewer noted, they push out and are not useful at the beginning. Once dry, yes they will stay down.
I would not buy these again, stick with carboy caps.

Fits but pushes out
I like the "universal-ness" of this product. However, when I first do a batch and the neck of the carboy is still wet from sanitizer, these have a tendency to push out and just barely rests on the top of the carboy. I have to use a rubber band to secure it in the beginning.
