Product details

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.

Careful packaging

Recently I purchased 2 siphonless 1.4 glass fermentors only to realize that these will solve oodles of problems down the road . So I waited til the next coupon appeared and ordered 4 more...along with some other necessities. The packaging was carefully done. Aside from someone crushing the box nothing was going to damage the glass. I'm very satisfied with all the products I ve purchased here over the years.

First time with wine

Great instructions, everything marked well so you couldn’t get anything wrong. Had some friends taste it, just before bottling. Really good flavor. I will be doing this one again.
