As a backup Incase the PET closure doesn’t fit.

Because it was presented as an option when buying the FerMonster and it was easy to add to cart. No other reason.

Works great with my FerMonsters. Make sure you put it in while lid and stopper are both DRY and works great.

Essential for Fermonster
Essential bung for the Fermonster. MoreWine doesn't carry the Medium Universal Bung so this is the one you need.

Best Stopper on the Planet!
Yup...it's a stopper. Strange I would be asked to review it. It works. All I can ask for.

Is it just me?
It’s a stopper. It’s fine, but these don’t fit quite right in my 6 gallon carboys. They pop out unless I jam them in so far that I need a tool to get them out.

Great stopper
I use this stopper on my Fermonster carboy and it works great!
January 15, 2018
Fits my carboys and seals out the germs. Airlock fits snug. No problems. Does exactly what it is supposed to do, and what you'd expect it to do.

Perfect fit for Better Bottle
These are a must have for Better Bottles. They can push pretty far down into the mouth of the carboy and become difficult to get out. It would be nice to have a lip around the top of the stopper to prevent it from going too far down and to give you something to grab hold of to pull it out.

Great for 5- and 6-gallon PET plastic carboys!
I use PET plastic carboys, and these stoppers make a great seal. They are easy to clean and sanitize. They are very durable as well. I love these stoppers.
