Abstract
A seal including a seal wall comprising a swelling polymer material having elastomeric properties so that the seal has a non-swollen state and an expanded state, the seal wall having a closed circumference that extends around a central longitudinal axis and that extends from a first end via an intermediate section to a second end along a length (L) in the direction of the central axis (A), wherein the first end of the seal sleeve wall is connected or connectable to the inner element and wherein the seal wall, apart from at and adjacent to the first end thereof, is freely radially expandable due to the fact that the second end and the intermediate section of the seal wall are not connected to any structural parts.
