A hydraulic sample mounting press utilizes a face seal against the top face of a molding cylinder. The face seal employs a hydraulic cylinder to press a disk-shaped surface of a cap piece against the top annular face of the mold cylinder for a metallographic mounting press. The face seal cylinder is mounted to a hydraulic fluid column that allows the face seal to rotate away from the mold cylinder for access to the molding cylinder and to rotate into place when a metallographic mount is to be molded.
