ABSTRACT:
A novel annular seal packing ring, frustoconical in form with a parallelogram cross section. When loaded into a rectangular seal gland groove, the smaller diameter end is biased radially inward and the larger end is biased radially outward against the gland. The bias is developed primarily in a centrally encapsulated annular spring band. The largest outside diameter and the smallest inside diameter constitute the sealing surfaces of the seal ring.
