Great for holding cleaning solutions in your carboy or keeping dust out during storage.
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 undrilled universal bung will work with glass carboys.
Top Diameter: 1.56"

Customer ReviewsWrite a review
I purchased these stoppers for the 3 gallon carboys and they work great. I’m using them to collect Hydrosol (distillate) from the essential oil making process and they work perfectly. If you’re using them for a similar purpose just make sure there is a dry surface on the bottle and the stopper, even a drop of oil will break the seal. When used dry these stoppers are a great fit and have a tight seal. P.S. Their customer service is stellar in my experience!
Yup. These stoppers do a good job of plugging up my carboys and keeping air from getting in. They’re made of a tough, flexible plastic that will give you years upon years of service.
