Too big for the 5000 ml flask
I have seen this stopper listed for the 5000 ml flask in the past, but it seems too big. The #11.5 stopper works much better.

I am sure this is a fine stopper for other applications.

Doesn't fit the the 5000L flask to well
I'm sure this stopper works like any other stopper if you get it to seal. I had the same problem as the first review that it keeps popping out. I use a foam stopper that has been soaked in Star San and it works great!

A little too big for a 5L Flask
it is just a little too big to create a tight seal with my 5L flask. It keeps popping out.

Perfect fit for 5000ml flask
I bought this to fit my 5000ml flask and it is the perfect fit so I can add an airlock.
