Wait, why are Viton not ok for UHV? Viton KF seals are used everywhere for UHV (maybe not to the -12 but -10 is definitely achievable).

  Viton leaks water. The only way I can see getting to -10's with Viton seals is having a tiny small amount or a huge pump.

    Understandable why this is a issue for a homelab but most industrial UHV chamber have cryo for this reason.
