Abstract: A method of manufacturing a sealing element for use in a fluid conveyance device comprising the steps of: forming an elastomeric sealing body including a first body portion defining at least one annular sealing rib, and a second body portion arranged on an end of the first body portion, the second body portion comprising an annular protrusion extending radially beyond the first body portion; and forming a layer of barrier material on a free end of the second body portion, wherein the forming steps are carried out in a single molding operation.

Abstract: A sealing article for use with a fluid conveyance device comprises an elastomeric body including a first end defining a disk-shaped annular protrusion, and an annular recess formed in a sidewall thereof directly adjacent the first end of the body in an axial direction of the body. The recess is sized to receive at least a portion of the annular protrusion in response to the sealing article being inserted into an interior cavity of the fluid conveyance device. A barrier material is attached to or formed on a first end of the body and extends over the radial protrusion.
