Abstract:
1. A seal comprising an elastomeric seal body with a first planar surface, a second planar surface substantially parallel to the first planar surface, and a sealing surface adjacent to and substantially perpendicular to the first and second planar surfaces, a plurality of generally planar inserts having planar side faces that are arranged substantially perpendicular to the first and second planar surfaces, the planar side faces having a length dimension and a width dimension, and wherein the length and width dimensions of the planar side faces are both greater than a thickness dimension of the generally planar inserts, wherein the plurality of generally planar inserts are arranged in a first arrangement of a plurality of generally planar inserts embedded within the elastomeric seal body adjacent the sealing surface and the first planar surface of the seal body, and a second arrangement of a plurality of generally planar inserts embedded within the elastomeric seal body adjacent the sealing surface and the second planar surface of the seal body, and having elastomeric seal material disposed between the planar side faces of the adjacent generally planar inserts in each of the first and second arrangements, wherein each of the generally planar inserts in each of the first and second arrangements comprises a first edge exposed at the sealing surface, wherein the generally planar inserts in the first arrangement are spaced apart from the generally planar inserts in the second arrangement.
