Hi from cold Norway.

I am into some Copeland Copelamatic's 1.5hp compressors. I have to install them in a very narrow space on a -85c freezedrier so I will reuse the old Rotalock's. The new ones have a kind of figured metal gaskets between the Rotalock's and the body. The paper gasket I am used to is simply gone. Due to the high pressures on the 508B circuit and a cooling failure after loosing may be 10grams, it is important to be sure that the Rotalock,s does not leak. I have no experience with the new gasket style It is not to many users of Copelamatic here so I hope that may be someone out there can give me a go or not for using them. If not, I have to make 4 new gaskets since they are not common here either.
