Medium Drilled Universal Carboy Stopper


A medium universal stopper is a handy homebrewing accessory that is compatible with 5 or 6 gallon PET Plastic Carboys. A carboy stopper provides a seal on your fermenter, while allowing CO2 to escape through an airlock.  

The drilled hole fits a 3-piece airlock, like The Hex, or a twin bubbler airlock. or A universal stopper’s unique shape and longer taper provides a snug fit and better seal, making it less likely to slide or pop out of place during fermentation. This medium universal carboy stopper features a lip that prevents it from falling or being pushed into a carboy.

BPA Free, made of silicone.
