The lower ceramic washer acts like a piston to compress the sealant when the nut on the central post is tightened. The Belleville washers serve to maintain a minimum tension on the central post. A top ceramic washer is held in place by the tension in the central bolt as long as the tension exceeds a minimum value. |
