Fastrack 3 Piece Airlock for Fermentation Hydrolocks for Fermenting Wine and Beer with Drilled Rubber Stopper Durable Carboy Bung with transparent Airlock Set used for Fermentation Set of 3

These work great for my home winery with one gallon jugs.

I use them for making Wine and Mead; they're better than the old-fashioned balloon method, if you know what I'm referring to. They do the job well.

I believe these are better than the other type of airlocks because they are easier to clean. The bungs are sized so they fit in Amazon juice bottles just fine (ha).

It’s more of a 4.5 than a 5. The only thing that annoys me, these things are way too fragile. I’ve cracked a few. Other than that, I love these vs the s-shape.

These perform great and hold a large amount of liquid. I did get one cracked and contacted the company on the card they sent. It took them about 11 days to respond saying they will send out another. Then another 10 days later I got 2 in the mail. Great customer service just a bit slow on the response.

They worked quite well

Great product

I live that it’s easy and perfect size. The product doesn’t overflow or have leak so you’re safe with fermentation. Make sure to put a liquid that’s food safe and mold safe.
