    Abstract: A sealing arrangement for providing a fluid tight seal between the rim of a skirt or like member and a second member is in the form of first and second resilient concentric rings for mounting on the rim. The first ring is a sealing ring which has an annular face intended for sealing engagement with the second member. The second ring is radially displaceable so as to accommodate changes in dimension of the first ring when the first ring is deformed by the first and second members being urged together under pressure. In an embodiment, the annular face includes one or more sealing lips protruding from the face.
