It stays in better than rubber and doesn't smell. To Sanitize I just place it in my Star San bucket.

Only bung I'll use Review by Holly berries

This style bung works way better than the other rubber style! It doesn't pop off the carboy when it's wet, and because it has a lip it cant fall into the carboy! For pennies more why not buy thus one!

This bung works exactly as described. Great snug fit in my 6 gallon glass carboy. Despite what other reviewers have said, this bung has no compatibility issues with the "S" shaped air lock that I have (which is the one from Midwest). Great value.

It fits tightly, just jam it in, then gently jam in the air lock. It stays in place the whole time.

Almost Universal Review by Mason

I use the small universal carboy bung on .5, 1, 3.5, 5, and 6.5 gallon fermenters. I find this product to be very useful, but it does not fit snugly to an s-bubble air lock. A #6 bung will work as a an adapter between a s-bubble air lock and a small universal bung.

Fits my Better Bottles Review by Dobson

I have no problem with sanitizing it in Starsan and then sticking it in and it staying in and not popping out. It works fine, and holds an S-lock without problem.

Works on my Better Bottles Review by Redmond

I jam it in hard then put in the air lock. It fits and holds tight. Can't beat the price either.

Not so great Review by Matt

(Posted on 11/12/13)

Product Rating:

After about 5 batches going through the carboy I've noticed this bung doesn't seal as well as it did when I first got it. I've cleaned it correctly after each use; however, it seem like it fits tight but my airlock has natural pressure, but if I move the bung and find the "right spot" the airlock then gets positive pressure. Overall, it's annoying. Guess I'll have to replace these after every few batches.

Can be used on different sizes of carboys! Review by Cathie
