Does not fit on the regular 1 gallon Growler or Carbouy
The cork are available in 3 sizes. Please measure your growler/carboy and order accordingly. You can return this cork if it does not suit you
it not so good with plastic bottle the gases in side the bottle keep pushing it out ,probably it will snug fit on glass bottle
Dev you can use some food grade packing to create a tighter fit. Glass is Harder than plastic which makes it tight fit
