The gasket includes a retainer and a generally annular seal element received in a groove formed into at least one side of the retainer. Such retainer side further is formed as having one or more channels extending extend radially through the groove and the inner or outer perimeter of the retainer. Each such channel defines a vent for relieving hydrostatic fluid pressure as the gasket is compressed between the interface surfaces.
