3-Piece Air Locks are the standard airlock for home fermentation and fit in most fermenters using grommets, bungs, and stoppers designed to take an airlock. Simply fill with water, vodka, or no-rinse sanitizer to the max fill line to allow CO2 out through the liquid in the airlock during fermentation, while not allowing oxygen or wild bugs like yeast or bacteria in.
