Abstract
A flexible seal assembly has an elastomeric body with a convoluted intermediate portion for accommodating pivotal movement about the center of a spherical joint and an integral radial seal lip for accommodating rotational movement about a central axis of the joint. The seal lip extends from an inner diameter portion of elastomeric body in proximate relationship to a rigid plastic lip restraining ring which is molded into such inner diameter portion such that flexure loads are carried by the restraining ring and have no effect on the seal lip.
