Buon Vin Home Brew Ohio Drilled Rubber Stopper, Carboy Bung (Pack of 3), White, (N5-KZEO-H88I)

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.)

works lie it should

Great to use with my 1 gallon carboy s.

I decided to order the product after seeing the favorable reviews and the low cost of the product. However, I just got one stopper as opposed to the three as promised in the description. The packaging was flimsy. The delivery also took longer than promised. The one stopper I received is also damaged. Gave one star because I can't go lower than that.Edit: I received a replacement of 3 stoppers after speaking to the customer service at homebrewstuff.com. I am satisfied with the quality of the stoppers. Although they don't fit 1 gallon juice containers, they fit the 0.5 gallon containers perfectly. I have already started a grape-cranberry wine brew. Cheers!

Use these with my 5 gallon fermentators and S-locks

The fit was perfect

I ordered a 6-gallon Better Bottle carboy and these stoppers plus some airlocks were shown in the "order this product with these items for this price" area and I went ahead and added to the cart. I did not look to make sure they were the correct product. I just assumed that Amazon would pair the correct stopper to the bottle.I will not make this mistake again.The product was sent promptly, packaged well and I'm sure the product itself is good. I'm keeping them on hand for possible future use. It just wasn't what I was expecting.I give three stars for Amazon's confusing product placement.

Made my own CO2 system for my fish tank. Standard fish tubing is too small. You will need to buy some 3/8" tubing to fit in the hole. If you are building a CO2 system, here is how I did it:Fill growler with a 1/2 quart of warm water, 1.5 cups of sugar, and one packet of yeast. Cap on, shake well. Stopper in, carefully pound into bottle, then add 3/8" hose. Hose should be a few inches above the water. Route the tube into the aquarium and after a while, you will see the water start to escape the tube. That is the build up of CO2 working through the tube. By the next day you should have CO2 bubbles every few seconds or so.This system has worked well for over a week now. I plan on changing the bottle every two weeks or when the CO2 stops bubbling.

I like them they are great
