Small Universal Carboy Bung- Solid
The Small Universal Carboy Bung- Solid works on the 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 is solid so you won't be able to install an airlock. The lip prevents the bung from falling into the carboy. The bung will seal a carboy even if it is wet.
