Abstract
A replaceable sealing member is disclosed which includes a body, lip seal and bonded reinforcement section having a skirt portion and a lip support surface. The skirt portion and lip support restrict elastomeric flow of the body and lip seal portion of the sealing member to prevent extrusion damage. A radially extending flange, from which the skirt portion axially projects, is bonded to the body and has an abutment surface on one side for abutment against a shoulder in a metallic support, such as in a mud pump piston hub, for limiting axial movement of the replaceable sealing member.
