The sleeve is provided at least at one end with a portion projecting into the material of the housing, such projection being preferably in the form of an annular bead with a corresponding internally disposed groove. The other end of the sleeve has an internally radially projecting flange projecting into the material of the housing, and the elastomeric O-ring is disposed at the junction between the internal surface of the flange and the surface of the sleeve bore to provide a seal for the pressure end of the cylinder.
