Drilled to accept an airlock (#7008 and 7010).
Universal bungs have a longer taper than standard rubber stoppers, for snugger fit and better seal — plus a lip prevents bung from falling into carboy.
This drilled universal bung will work with glass carboys.
Top Diameter: 1.56"
Bottom Diameter: 1.156"
