Plastic Carboy Bung - Solid

Universal bungs are a tighter fit and better seal as well as a lip that prevents the bung from slipping into the carboy. Seal easily when wet. Fits standard plastic carboys (BB001 / BB002 / BB003) and our FerMonster Wide Mouth Plastic Carboys (CB061A / CB061B). Perfect to use when aging your beer/wine post fermentation.
