Designed for our 2 Gallon Systems.


No need to guess when fermentation has stopped.This professional grade 3-piece airlock is easy to clean and virtually silent. It will show the difference between the inside air pressure and the outside air pressure (a great way to gauge fermenting activity), and it can also prevent “suck back” (a term used for when liquid in the airlock is sucked into the fermenter due to temperature changes). Not to mention watching the bubbles is a great way to pass the time while you’re waiting for your beer to complete fermentation.



  • 3-Piece Airlock
  • #3 Rubber Stopper
  • Airtight Gasket for Fermenter Lid (3 gallon fermenter only)


Brewing Note

The lid gasket was designed to work with our Little Demon 3-Gal Conical Fermenter (2 GALLON BREWING SYSTEMS). Sanitize everything (inside and out) before using.

AIRLOCK INSTRUCTIONS 1. Sanitize The Airlock Sanitize everything (inside and out) before using. 2. Adding The Airlock After you have made your beer and added the yeast. Tighten down the lid, then add the airlock. 3. Filling The Airlock After the airlock is firmly in place, add water to the fill line(s). Sanitized water or alcohol (like vodka) is preferred. (F.Y.I. if need be, refilling it with regular tap water should be fine). 4. Removing The Airlock Remove the airlock (and/or loosen your lid) BEFORE opening your tap for any reason. Completely remove the airlock before bottling your beer. WARNING: ALWAYS REMOVE THE AIRLOCK WHEN OPENING TAP, OTHERWISE LIQUID FROM THE AIRLOCK WILL WIND-UP IN YOUR BEER.

Makes 2 gallons of wicked-good beer in just 14 days!
