A sealing arrangement between a screen changer strainer and a clamping body in which an annular rib on a sealing plate abutting the strainer fits in an annular groove in the clamping body and a hydraulically displaceable material is confined in the space between the end face of the rib and the bottom of the groove. As the clamping body is pressed against the strainer and undergoes distortion creating areas of high and low pressure around the rim, the material in the groove is displaceable circumferentially of the groove to distribute the forces evenly around the face of the rib abutting the strainer and thereby provide a tight seal and an even distribution of forces on the strainer.
