The assembly includes at least one sealing lip having an abutment surface and a wearstrip disposed along at least one of the interior base surface, the first and second interior leg surfaces, and the abutment surface and formed of a thermoplastic polyethylene material. The wearstrip has a plurality of alternating wear sections and gaps that define a series of alternating semi-rigid and flexible sections, respectively, with each wear section having first and second surfaces. The first surface of one of the wear sections and the second surface of an adjacent wear section face each other to define the gap.
