The #7 stoppers pop out and the #6 fall though my 3 gallon carboy. I figure this has to work.

Italian glass carboys won’t fit a 6 or 7. Maybe I’ll get lucky.

Get these to make a leakproof blowoff with Duotight fittings.
This stopper is perfect for my plastic fermenter. Best of all, I was able to screw in a Duotight tubing fitting for a quick, neat blowoff tube assembly. You can use this in many vessels in a similar fashion, the center hole will take a 5/16 device - you could use for spunding valves. The material it is made of doesn't seem to lose its' pliability over time which is critical for a quality, reliable seal.
