Hi all,
So I've been using a stainless steel fusti (Sansone model) as my fermenter. It works great, nice internal welds, easy to clean etc etc.
The lid screws down and has a rubber gasket to form a seal. Only thing is it doesn't seem to hold a completely airtight seal. I've tested it lots and under any kind of minimal pressure (eg. blowing air through the spigot opening) air leaks out from the seal.
I know a lot of people don't feel a completely airtight seal is necessary for a fermenter. And I'm fine with that. But I wanted to try doing a pressure transfer from the fusti - so wanted to have it seal properly.
I purchased a fatter silicone oring (that is perhaps slightly too large diameter) but this didn't help.
Pictures attached. Any ideas?
