Drilled to accept an airlock (#7008 and 7010).
Universal bungs have a longer taper than standard rubber stoppers, for snugger fit and better seal — plus a lip prevents bung from falling into carboy.
This drilled universal bung will work with glass carboys.

1 year agoDoesn't seat well at allThese bungs don't seat well! I noticed all the 5 star reviews are from back in 2014 and before. Maybe they got a different supplier, but these guys aren't staying in my carboys even dry. I sure don't want to ruin a $150 batch of wine over a $1.50 bung. May have to start using the rubber ones.December 20, 2016Purchased
over 2 years agoThe rubber is hard and not very sticky. This causes it to slide upward and not seal well. After soaking it in some Oxy it became a little more sticky and now seals OK. My old one I bought locally sealed from day one and is my still my go to after 3 years.December 18, 2016Purchased
over 3 years agoDoesn't pop outIt stays in better than rubber and doesn't smell. To Sanitize I just place it in my Star San bucket.April 2, 2014Only bung I'll useThis 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!March 7, 2014Bung for CarboysI use one of these with my 5 Gallon glass carboy, works, great, just make sure its in tight.. otherwise it can slip outMarch 4, 2014Works Well!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.March 2, 2014Low CostIt fits tightly, just jam it in, then gently jam in the air lock. It stays in place the whole time.February 7, 2014Almost UniversalI 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.January 25, 2014
