ABSTRACT:
Anti-rotation device consists of a thin washer having a pair of circumferentially and radially spaced tabs protruding axially from one side thereof which are adapted to be received in the gaps in the inner and outer rings, respectively, of a circumferential ring seal to prevent the gaps from aligning themselves. The tabs are desirably located approximately 180.degree. apart to keep the ring gaps on diametrically opposite sides of the seal.
