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!
