Abstract
An annular elastomeric seal-ring construction having a body adapted for stabilized retention in a circumferential seal-ring groove in one of two relatively rotatable members and for circumferentially continuous resilient contact with an opposed wiping surface of the other member. The resilient wiping contact is established via an integral rib of width less than body width, wherein the locus of the rib undulates axially as a function of azimuth about the axis of the ring body.
