<p>A face seal (10) comprises a first half and a second half. Each half of the face seal comprises an inner sealing ring (20), the inner sealing ring (20) being generally L-shaped in cross-section, an elastomer ring (30) disposed over the inner sealing ring (20), and an outer ring (40) disposed over the elastomeric ring (30), the outer ring (40) being generally Z-shaped in cross-section. The inner sealing ring (20) comprises an axially extending circular cylindrical portion (21), a radially extending planar ring portion (22) coupled to the cylindrical portion (21), and a sealing surface defined by the seal side planar wall (26). The outer ring (40) comprises an axially extending second circular cylindrical portion (41), a seating flange (42) extending radially outward from a front end of the second cylindrical portion (41), and a backing flange (43) extending radially inward from the rear end of the second cylindrical portion (41).</p> |
