A wiper seal for a hydraulic component is provided. The wiper seal includes a support member with a first leg that has an inner surface, a first end, and a second end and that extends substantially parallel to a reference axis. The support member further includes a second leg that has an outer surface extending substantially perpendicular to the reference axis from the first end of the first leg. The wiper seal also includes a body portion that defines an opening therethrough and includes an outer peripheral surface configured to receive the inner surface of the first leg of the support member. A first radial face extends substantially coplanar with the outer surface of the second leg and a second radial face extends generally perpendicular to the reference axis from the second end of the first leg of the support member. The second radial face includes a cutout defining a first cavity. An inner surface defines a first sealing lip adjacent the first radial face. A projection extends from the inner surface to a second sealing lip. The second sealing lip is separated from the first sealing lip by a second cavity.
