The crush washer is of a different metal. I dont have it hear, but it is either aluminum or Stainless steel.

Your asumptions are right on. We too are concerned about redidual gas entrapment after sealing the metal joints. Hopefully the amount of entraped air would be so minimal as to be absorbed by getter material.

I have a 16gp4 that has milky getters. Presumably from a leak. But it still produces a very good picture. So, it is possible that if the getter flashes are very large, we may be able to counteract the infiltration of any small amounts of gas that might get entraped in the ultor ring after it has been sealed.
