ABSTRACT:
The invention relates to a fluid tight pipe connection having an intermediate ring between the two pipe ends. By making the two surfaces of the ring complementary to the pipe end faces the ring may be displaced in relation to one pipe end and may be moved pivotally in relation to the other pipe end to enable the connection to allow for angular misalignment and parallel offset of the pipe axes while still maintaining a sealing joint.
