ABSTRACT:
A seal for vacuum flange connections includes a plastically deformable seal ing and an associated ring designed to ensure that the seal remains tight even upon cooling after a previous heating. This is obtained by providing a support ring having two resilient retaining portions, each for one plastically deformable seal ring. The design makes it possible to repeatedly use and re-use seal rings, which preferably are made of metal for example, gold.
