A gasket assembly includes a one-piece gasket that has a mounting end, for mounting to an associated enclosure body, and a pipe engaging end, for receiving an associated pipe. An intermediate section is located between the mounting end and the pipe engaging end. A mounting element is of one piece with one of the mounting end, the pipe engaging end and the intermediate section. A clamping member is used with the gasket. The clamping member is looped to assume an annular configuration. A retaining member extends through an aperture located in the mounting element and through the clamping member for retaining the clamping member to the gasket in a transport position of the gasket assembly.
