Abstract

An annular seal for use in a twin tube shock absorber comprises a radially inner face upon which primary and outer, piston rod contacting sealing lips (21, 23) are formed. A radially outer part of the seal has a depending lip (27) which extends in use generally axially of the shock absorber and which can engage a secondary sealing element (29) secured to a rod guide (11). A cavity (45) defined by the rod guide (11), piston rod (13), primary sealing lip (21), secondary sealing element (29) and depending lip (27), is filled with hydraulic fluid at least sufficiently to immerse the primary sealing lip (21) and thereby improve its life. When the fluid pressure in the cavity (45) is sufficient, the depending lip (27) is deflected to allow fluid to pass into the reservoir (9) formed between the tubes (1, 3). However, at all times the primary sealing lip (21) is advantageously immersed in hydraulic fluid.
