<p>A seal (26) is provided having a back surface (32) that is generally perpendicular with a longitudinal axis (34) of the seal (26) and a sealing portion (30) on the side opposite the back surface (32). The sealing portion (30) is defined by first and second intersecting surfaces (40,42). A plurality of projections (44) are disposed on one of the first and second surfaces (40,42) at a location generally adjacent the intersection of the surfaces (40,42) and a cylindrical recess (50) is defined in at least a portion of the plurality of projections (44). The sides of the cylindrical recesses (50) and the plurality of projections (44) are oriented perpendicular to the back surface (32) to enhance the ability to manufacture the seal (26) in an economical manner.</p> |
