Abstract

In a suspension strut a piston-rod works through an elastomeric seal at the inner end of a tubular extension which depends from an end plug closing the upper end of cylinder. The seal comprises a collar which encircles the free end of the extension and is provided with a depending, contiguous, radial sealing flange which overlies the free end of the extension. The flange may be encircled by a retaining ring which enhances the grip of the flange against the rod, and the collar may be stiffened by a metal tubular former embedded in the material of the collar.
