Medium Drilled Universal Carboy Stopper
$2.29

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.
