ABSTRACT:
A housing assembly is provided that has a case including an open end and a flange extending around at least a portion of the open end. The flange defines at least one reduced area extending into a portion of the flange, and a gasket is disposed around the flange. Preferably, the gasket includes a first sealing portion, a second sealing portion, an internal groove for receiving the flange, and at least one member extending into the internal groove and into the at least one reduced area of the flange. In one form, the reduced area is an aperture, and the member of the gasket is a support that extends all the way through the flanges, thereby providing a secure engagement between the gasket and the case during operation. Methods of manufacturing the housing assembly are also provided.
