Abstract: A sealing device (10) for providing a fluid-tight sealing of a joint comprising a first part (30) and a second part (32) with a relative movement in between. The sealing device (10) comprises: an outer sealing part (12) designed to contact the first part and the second part, an inner sealing part (14) designed to contact the first part and the second part, and a spacing structure (16) connecting the outer sealing part (12) and the inner sealing part (14). The outer sealing part (12) and the inner sealing part (14) define an intermediate space (18) between the outer sealing part (12) and the inner sealing part (14). The outer sealing part (12) and the inner sealing part (14) are being configured to seal off the intermediate space (18) from both an exterior and an interior of the joint, and the intermediate space (18) is configured to be influid contact with both the first part (30) and the second part (32).
