ABSTRACT:
A multiple element seal ring system comprising a pair of pressure non-deformable split rings and a deformable expander ring adapted to be received in a groove. The split rings are provided with relatively narrow inner surfaces spaced from the groove bottom wall to provide clearances of short axial extent therebetween for restricting deformation of the expander ring within its elastic limits.
