Abstract
The embodiment of the invention disclosed herein is directed to a mounting grommet for an electrical heating element used in appliances such as dishwashers and the like. The mounting grommet is formed of a resilient body portion of a size to be forcibly urged through an aperture formed in the bulkhead of the appliance and forming a seal therewith. A neck portion is formed integral with the resilient body portion and has an axial extent substantially equal to the thickness of the bulkhead receiving the grommet. The neck portion is of a diameter substantially to fill the aperture formed in the bulkhead. A head portion is formed integral with the neck portion to overlie the aperture on the side opposite that of the resilient body portion. A passage is formed axially through the body portion, neck portion and head portion to receive the end of a heating element therethrough. A flared tubular ferrule or conical tubular ferrule is provided at the end of the body portion to receive sealing cement for permanently securing the mounting grommet to the heating element inserted therethrough.
