Airlocks for Fermenting, Brewing Supplies, Super Transparent Upgraded Version of 4 Fermentation Airlock, 4#6 Stoppers and 8 Airlock Grommets, Used for Brewing Wine, Beer, Sauerkraut, Pickles, Etc

Works well, fits the 1gal carboys just fine. Be sure to rubber band them down as vigorous ferments will push any airlock off. They also help show when the fermentation is done.

Perfect for Fermenting — Simple, Reliable, and Effective! I absolutely love this Bubble Airlock Set! It’s a must-have for anyone who brews, ferments, or makes homemade wines, beers, or kombucha. The airlocks are sturdy, easy to clean, and fit perfectly on standard-size lids and bungs. They allow gas to escape smoothly while keeping contaminants out, which means no more messy or risky fermentation setups. The clear design makes it easy to monitor bubbling activity and know exactly when fermentation is active or slowing down. I’ve used them for sauerkraut, mead, and cider — and they worked flawlessly every time. Great value, great quality, and super dependable. Highly recommend for beginners and seasoned fermenters alike!

Just what I needed in a timely manner

Nice heavy duty airlock, not the skinny wimpy ones. I did have one that the red cap was cracked and does not snap onto the top. I dont know if I can get one new red cap to replace it.

We purchased these for wine brewing and they worked great! No issues at all. Easy to use, easy to clean and they fit our bottle perfectly.

Inexpensive but effective. I made fermented hit sauce and this air stop was key

Works as advertised. Fits those carlo rossi wine bottles too, so you can just get one of those and use it after you drink the wine.

I love these airlocks, and I will buy them again. Great buy.
