Abstract
In a fluid-operated device such as a gas spring a piston rod is axially movably guided through a passage in an end wall of the gas spring. A sealing disc of elastomeric material is axially compressed between two supporting faces and engages the piston rod with a convex radially inner edge. The apex of the edge is substantially midway of the axial thickness of the sealing disc. Preferably the sealing disc has also a radially outwardly convex sealing edge which is in sealing engagement with a stationary face surrounding the sealing disc.
