Johnson Truck Bodies has announced design and development of a new triple sealing point door gasket that simplifies door opening/closing, and is effective in limiting heat and moisture transfer that enters the refrigerated truck body.
Instead of a single contact point, the new TripleSeal door gasket has three sealing points: an outer “bulb” that seals against the outer door frame, a center contact point that seals on the center of the recess, and a large third sealing point that seals between the door pan radius and door frame inner radius.
Now standard on all Johnson refrigerated truck bodies, the TripleSeal gasket has proven effective in solving a door-opening problem created with a warm, humid ambient outdoor atmosphere, and a driving rain combined with a dry/very cold or frozen environment inside the truck body. In refrigerated delivery are many stops and door openings during a daily route, and the above condition creates a low-pressure situation inside the truck body that frequently “sucks,” or pulls the outside elements past traditional door seals and into the body. With the TripleSeal gasket, the potential for heat and moisture to enter the body is reduced, improving thermal efficiency.
Extruded in neoprene rubber, the new gasket's softness and compressibility reduce the effort required to operate the door handles each time doors are closed and opened. This enhances driver safety, and since less pressure is required to close the doors, the potential of a door handle swinging or kicking back on the driver is eliminated.
