A seal comprises a resilient sealing member (1) adapted to bridge an annular gap between two relatively rotatable concentric parts (6, 9) so that it is loaded in bending and is resiliently urged into sealing engagement with one of said two parts. A dust seal (5) is formed integrally with the sealing member (1) and extends away from a side face of the sealing member (1) at an angle. When assembled between said relatively rotatable parts (6, 9), the sealing member (1) is deformed axially to form an annular seal at its free peripheral edge, and to move the dust seal (5) so that its free peripheral edge (10) is located closely adjacent to or touches the other rotatable part. The sealing member (1) may be a flat disc or a frusto-conical shape. The invention may be used in a shaft seal or a face seal.
