A sealing system for sealing high liquid pressure and containing a wiper lip (68 or 69a and 68a) in either of two forms. The light pressure seal includes a seal casing, a seal body (40) including a lip seal (54), a snap ring (66) and a plastic back-up ring (42), and the wiper lip seals on either a radial (68a) or an axial surface (69a). The casing may have radial (32) and axial (30) flanges or a radial flange only. The space (85) between the two seals may be filled with grease.
