Abstract
An electric resistance heating element for use in appliances such as dishwashers includes a mounting grommet having a resilient body portion sized to be forcibly urged through an aperture formed in a bulkhead of the appliance. A neck portion formed integral with the resilient body portion has an axial extent substantially equal to the thickness of the bulkhead receiving the grommet and a width to substantially fill the aperture. A head portion formed integral with the neck portion overlies 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.
