Product Description
The Three-Piece Airlock is a versatile and easy-to-clean fermentation tool for homebrewing and winemaking. Fill with water and insert into a drilled rubber stopper or carboy bung to safely vent carbon dioxide while keeping oxygen and contaminants out during fermentation.
Unlike one-piece styles, this airlock disassembles quickly for cleaning—making it ideal for active fermentations where krausen or blow-off may occur. It includes three parts: the outer chamber (body), floating piston, and vented cap, all made of food-safe plastic.
Perfect for use with: carboys, fermentation buckets, and rubber stoppers or bungs. The Three-Piece Airlock is especially popular with brewers who prioritize easy sanitation and quick reassembly between batches.
Whether you're fermenting a 1-gallon wine or a 5-gallon beer, this reliable airlock ensures your fermentation stays safe, sealed, and on track.
