Small Universal Carboy Bung for Glass Carboy – Drilled

A good solution when a 6.5 sits too low and a #7 sits too high.  The lip prevents the bung from falling into the carboy. Works on 3, 5, 6 and 6.5 gallon glass carboys.  These bungs have a graduated taper which provides a snug fit and seal on any size Carboy.  This bung will seal a Carboy even if it is wet. No worries about having the right size bung for your carboy. It is already drilled for you to insert your airlock.
