AKA: Cylinder Airlock.: Simply remove the cap, fill the cylinder about halfway (to the imprinted line) with water or sanitizer, and replace the cap. 3-piece airlocks are easy to clean with an airlock brush if the fermentation backs up into the airlock.
We prefer this style for Primary or active fermentations, as they can easily be converted for Blow-Off Tube using 1/2" ID Tubing.
Please Note: Airlocks are sold individually, stoppers are not included.
