Medium Universal Stopper - Drilled
Plastic bung with a drilled hole for airlocks. This universal style has a longer taper than rubber stoppers, for a snug fit and better seal. Fits plastic carboys, Better Bottles and Bubbler PET fermentors. This bung is too large for the Big Mouth Bubbler® universal lid.
Universal bungs have a longer taper than standard rubber stoppers, for snugger fit and better seal. Plus a lip that prevents the bung from falling into carboy. The drilled hole fits an airlock (#7008 or #7010) for fermentation.
