My question is how you get that universal bung to stay in the carboy neck. No matter what I do it slips up and breaks the seal. I will say this… the drilled bungs I have from 20 years ago work a whole lot better than any version of the new ones. Not sure what the material is but it’s different.I have a 5 gallon moscato going and it was bubbling just fine (CO2 going right to left). Last night it had evened out, but this morning all the liquid is back on the right side (opposite of when fermenting). I am sure it is fine and going to rack it today, but curious as to why that happens.View attachment 100028

You need to have dry glass and a clean dry bung. I have better luck with the drilled silicone bungs. I keep a lot of different sizes on-hand.My question is how you get that universal bung to stay in the carboy neck. No matter what I do it slips up and breaks the seal.

I’ve dried the bung and neck with poor results. I even used rubbing alcohol to dry both the neck and bungI can often get the bung to stick by first drying the neck of the carboy and the bung with a paper towel. Then press it in and hold it for a few seconds.
Eventually, the bung acquires a "set" (i.e., is a little deformed) and so has less tendency to slip outwards.
