Yep, and thanks for that gem Samohon, I use one on my stripping still and it works great.
I'm just trying to get feelers out for all the different ideas, I don't have any personal experience with cork so I figure it's $20 well spent whether I learn the PTFE gasket is better or not. I'm a curious person, I like to try out all the different options just so down the line I can look back on what worked and what didn't.
Currently I'm trying different gaskets, I've used the typical flour paste, your PTFE, as well as some new ones like using lasagna noodles and cut tortillas. Cork is next on my checklist, but I may end up using it if I go to a larger column
And you may call me V
