A sealing ring (10) includes a plurality of circumferentially spaced axially directed projections (20) on one radial face thereof. In use, the sealing ring is located within a seating groove which is wider than the spacing between the radial faces (11,12) of the sealing ring, the projections (20) holding the ring against axial movement within the groove whilst allowing the ring to swell in the axial direction inbetween the projections so as to maintain the dimensional stability of the outer face (14) of the ring. The sealing ring is particularly useful in uni-directionally operative hydraulic dampers and door closers incorporating such dampers.
