Abstract
A one-piece seal is used between the rear doors of a semi-trailer truck and the rear frame of the truck, the seal having a good compression set resistance. The seal is made from multiple extrusion members that are fused, welded, or otherwise integrally, monolithically connected at corner joints to form a central opening. The extrusion members have a sealing profile, or cross-section, that allows for the compression and deflection of a pair of sealing lobes to create inner and outer seals, respectively, between the trailer frame and the door structure at the rear of a semi-trailer truck, as well as between the doors themselves.
