The 3 piece airlock is reliable, easy to fill, and easy to clean, compared to the triple ripple style airlock. For use during fermentation to allow gasses to escape from your homebrew, but prevent outside air from getting in. Use with carboys or buckets.

(Although most home brewers prefer the 3 piece airlock, we do sell the triple ripple type (16599) in case you are used to that type and would like to stay with it.)

Please Note: Stopper Not Included.
