Just realized Premium comes with its own stabilizing o-ring for inverted method!
Do it at your own risk since they don’t sell the o-ring separately!
Move the existing silicone ring from one end to the other for some extra stability while setting up for inverted method!
And it fits super nice!
Unscrew the end cap to make it easier to get the o-ring the first time.
Just never put it all the way back down and it is easier to slide back up the next time! You don’t normally go all the way anyways since there should be a puck of coffee that stops you close to here.
It only works to the end of the metal shaft before it gets smaller and then the plunger. So you lose a little space.
I was actually going to buy a separate 6” silicone ring when I realized this works.
If I ever break the o-ring I’ll either: not replace it, or get a generic 6” o-ring.
