The S Type Bubbler Airlock is a great entry level airlock. The one piece clear plastic unit that is 165 mm high, and fits with our standard ½" 12mm or 1cm Grommets for Airlock and the following HDPE brewers fermenters that we stock. 30 Litre Plastic Fermenter Works for brewing wine or beer or cider. Fill approximately half way with water or made up sanitiser. The water or made up sanitiser acts as a environmental barrier keeping bacteria and other unwanted contaminants out of your brew, while still allowing gasses to escape the fermentation.
