A sealing arrangement is provided for sealing a mounting groove formed in a first or second mounting member separated by a gap and defining a hydraulic passage. A gasket is mounted in the groove between the passage and gap. The gasket includes an annular gasket body having first and second axial ends and a buried reinforcement ring. The gasket body includes a unitary flange extending radially outward from the first axial end. The flange includes a first seal lip extending axially outward from the flange proximate the passage or gap. The first seal lip contacts a surface of the first or second mounting member facing the passage. The gasket body includes a second seal lip extending outward from the second axial end to contact a bottom surface of the mounting groove.
