Benefits of technology
The seal is made from a flexible material that can be easily installed and maintained. It is designed to stretch over the door and hold it in place, providing a fluid-tight seal that seals the inside of the trailer from the outside. The seal is weather-resistant and resistant to degradation by UV exposure. Overall, the seal ensures a tight and durable seal that is easy to install and maintain.
Problems solved by technology
Known seals for use on, for example, the doors of semi-trailer trucks are made from a thermoplastic that is not able to withstand extreme hot or cold temperatures.
Thus, such known seals are short-term in use.
Not only are these multi-piece seals expensive, the multi-piece seals are also difficult to install and maintain.
However, thermoplastic has poor performance in compression set, which is the measure of the material's ability to maintain deformation force over a long period of time.
Therefore, over time, the thermoplastic flap of the known seal will not maintain a sealing force against the frame of a semi-trailer truck.

Embodiment Construction
[0037]Large trucks, such as semi-trailer trucks, often need sealing units between rear door structures and a rear frame of the truck, as well as between the rear doors themselves. The present one-piece seal designed for installation on trailer doors for semi-trailer trucks is made of four individually extruded sections, or extrusion members. The extrusion members are heat fused or welded together to form a four-sided, one-piece, monolithic design having a closed profile. This one-piece design ensures that there is no leak path across the seal when the seal is placed on the semi-trailer truck.
[0038]While the seals of the present disclosure are discussed in terms of semi-trailer truck doors, other uses are also contemplated. For example, shipping containers, railroad boxcars and building doors may be used with seals made in accordance with the present disclosure. Moreover, any aperture or opening which is sealingly blocked with a cover of comparable size and shape may benefit from the...

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.
