ADVANCED AIRLOCK UPGRADE
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.
- (1) 3-Piece Airlock
- (1) #3 Rubber Stopper

The upgrade was designed to work with our 3 Gal fermenter. Sanitize everything (inside and out) before using.
