A process for creating a seal having a first linear portion and a second curved portion joined thereto is provided. The process includes providing a retaining section including a threaded metal wire with warp fiber disposed therein, forming the carrier section into a predetermined cross-sectional shape using forming rolls, extruding a polymeric material around the carrier section and generating a contacting member onto said carrier section to form a seal, heating the seal within an oven to cure the polymeric material and to break down the warp fiber so that the seal is readily bendable, and heating then cooling the second portion of the seal in a forming device for predetermined times at predetermined temperatures to cause the second portion of the seal to be formed in a curved manner.
