Bubble Airlock Fermentation Kit

4-Piece Fermentation Airlock Kit with #6 Drilled Stoppers, Grommets and B-Brite Cleaner

The Bubble Airlock Fermentation Kit is a complete accessory pack for homebrewing, winemaking, cider making, kombucha, sauerkraut, pickles, and other small-batch fermentation projects. This practical kit includes 4 bubble airlocks, 4 drilled #6 fermentation stoppers, 8 airlock grommets, and 35 g B-Brite cleaning powder to help prepare and protect your fermentation setup.

Each transparent bubble airlock allows carbon dioxide to escape during fermentation while helping reduce oxygen, dust, and airborne contaminants from entering the vessel. The included drilled stoppers and grommets make this kit useful for compatible carboys, fermentation buckets, mason jars, drilled lids, and custom fermentation containers.
