Patent ID: 8186691

Claim:
A seal for sealing between male and female couplers wherein the male coupler has a protruding tubular portion that is inserted into the female coupler during coupling, the seal comprising a retainer having opposite axial side faces defining a maximum thickness of the retainer, and radially inner and outer annular sealing elements made of elastomeric material integrally joined to the retainer, the radially inner sealing element having annular face sealing protrusions protruding axially beyond the opposite axial side faces of the retainer, and the radially outer sealing element having annular face sealing protrusions protruding axially beyond the opposite side faces of the retainer at a location respectively radially outwardly spaced from the face sealing protrusions of the inner sealing element, whereby when the seal is telescoped onto the protruding tubular portion and the male and female couplers are joined to one another, the annular face sealing protrusions of the seal will effect face seals between juxtaposed faces of the male and female couplers at radially spaced apart locations; and wherein the retainer has radially inner and outer peripheral portions, and an intermediate portion between the radially inner and outer peripheral portions, the intermediate portion having the axial side faces that define the maximum thickness of the retainer, which maximum thickness is greater than the thicknesses of the radially inner and outer peripheral portions.
