Arrangement for interconnecting two vacuum lines so that, after interconnection, the lines are rotatable relative to one another, which vacuum lines each comprise two concentric pipes 1, 2 with a vacuum in the space 3 formed between the pipes. The arrangement comprises a first end part, a male part, of one vacuum line and a second end part, a female part, of the other vacuum line. Between the male part and the female part, there is at least one O-ring 11 which is arranged in such a manner that it does not come into direct contact with a cold or hot medium flowing through the inner pipe 1. The invention also relates to male and female parts of vacuum lines intended for use in the connection arrangement. <IMAGE> |
