    Abstract: A seal assembly having an exclusion portion and a seal portion so that the assembly functions as both a sealing and exclusion device.

The exclusion portion, in combination with the seal portion, is shaped to prevent entry of contaminants into the system being sealed and to reduce extrusion of the excluder portion of the seal. Three different embodiments of the invention are disclosed using different elastomer energizer configurations.
