Product Description

This is a drilled tapered rubber bung for a better seal and holds the airlock securely in place. A curved lip stops the bung from accidently falling into the carboy. All three rubber stoppers are the same size and easily fits all 3, 5, 6 and 6.5 gallon glass carboys.

Customer Reviews

perfect for home winemaking
These specialized stoppers (with a hole for an air-valve) work equally well whether you are using 3-gallon glass jugs, or simple spring water "milk jug" like plastic gallon jugs from the grocery store. They fit either application perfectly.

They are conveniently sold in sets of 3 just like the airlocks (which I HIGHLY recommend to go with them- so much cleaner than the balloon-over-the-top method which left me with syrup and fruit going up into the balloon and all over my counter!).

These were amazingly effective when used together with "3 Piece Plastic Airlock (Sold in sets of 3)", and together, they did not coast much more than the baggie of balloons that they were replacing! I give them my HIGHEST recommendation for any home-brew or home wine-maker who would like a cleaner method of sealing their vessels to keep the sticky stuff and CO2 in and the oxygen out. (P.S. I can't get the product link to work for the airlock, but you should see it under the "buy together" option for this product. You definitely need them both together, not just one or the other.)
