as for other gaskets, why not, i dont know for pitchers, but why not try? all that can help barista is good
Teflon for a group gasket would be very hard on your wrists, it is not very merciful. Even as a rubber group gasket ages and hardens, the hardness is tough on the users joints, not to mention it doesn't seal as well. Teflon can easily withstand the heat. We use them on all of our heating elements and they last longer than the element itself, but that is a non-moving part. Othere places on the machine, like the steam swivel, would be great with teflon.
