Abstract: This invention is an improved sealing arrangement for use in conjunction with water closet rings wherein a lower section includes an inwardly beveled shoulder which fits a similar configured neoprene type gasket. When a specifically designed top section telescopically engages the interior of the lower section, the gasket is expanded to form a water tight seal about the drain pipe or other member associated therewith. Also provided is a clamping arrangement for a moisture impervious membrane.
