Fits 1 gallon jugs
I use this on a recycled 1 gallon glass jug. I noticed that the containers of organic apple cider from my local natural foods store are almost identical to those gallon jugs Midwest stocks. They are a couple bucks more at the store but that doesn't factor in shipping or the fact that I get juice. Anyways, these fit and I intend to buy more.

Solid Is Best
Okay, My shop NEVER had the right size, So I got a "universal bung" they work but they trap dust in the cup and spillage from the occasional over foam in the lock. Solid bungs are easier to clean and hold the heavier, glass airlocks better.

Long lasting and good product
I'm not sure what type of rubber these technically are, but they are dense, heavy, and very firm. Excellent quality. They don't seem to roughen up or breakdown over time._x000D__x000D_The only issue I've had is that you have to make sure the stopper and the neck of the bottle/carboy is very dry or they can creep up and out.

Best stoppers around
I like these stoppers better than other drilled stoppers. They seem to stick in the neck of the carboy very well and the airlock stays in solidly. I recommend.

Used for a 6.5 Gal Glass Carboy
These are solid bungs and are easier to clean. They hold the heavier, glass airlocks better. Since I keep beer in these for a year or more, that is critical to me.

Great to plug a hole
I have used these since the start of my brewing and they work great to keep out air. If you like simple and easy than these are for you.

For my 1 gallon experiments
These a durable and wont get roughed up and abraded over time. Dense and firm. Just make sure the mouth of the jug or carboy is not wet when you place in the plug,

Holds the grip well
The stopper is Excellent quality, its dense and firm. They hold the grip on the carboy well, and are air tight.

Nice and grippy
I've used both the universal stoppers and the drilled rubber stoppers. While it is annoying to have to find the right size stopper to fit your carboys (especially when dealing with abnormally sized carboys) the drilled rubber stoppers are made of a lovely solid grippy material. As long as the carboy mouth is dry when you put it in, there are no worries about one of these popping out.
