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"

Ordering was quick & easy. Shipping was prompt. The stopper is currently in use on a Pinot Grigio in secondary fermentation...working perfectly.
These are the best stoppers available! I’ve been using mine for years and I look forward to using them for years to come. They will make stopping up your carboys and inserting bubblers much easier. In fact, they’ll help you get hooked on wine making like me! So, make sure you buy enough of them for all of your carboys.
Works, simple, and necessary.
Seemed to do a fine job
