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.

An improved closet ring for use in conjunction with a pipe-type means comprising: a first section including a ring-like portion having a generally flat lower surface and an outwardly projecting closet flange disposed adjacent to a floor; a second section including a ring-like portion so sized as to telescopically receive at least a portion of said ring-like portion of said first section, said ring-like portion of said second section including a beveled, flat-in-cross-section, interiorly projecting shoulder coming to a point at its lower extremity; said pipe type means disposed adjacent to and interiorly of said telescoped first and second sections; a gasket means formed from a neoprene type resilient material and having a generally flat upper surface with a groove-like depression formed therein, said upper surface of said gasket being disposed generally juxtaposed to said flat lower surface of said first section, said gasket having at least two inwardly projecting sealing ribs lying juxtaposed to a portion of said pipe means, has an exterior lying juxtaposed to at least a portion of the interior of said ring portion of said second section, and has a lower, flat-in-cross-section, beveled portion coming to a point at its lower extremity lying juxtaposed to said flat beveled shoulder of said second section; means for creating telescopic pressure between said first and said second sections whereby said gasket will be force by said flat surface and said beveled shoulder into sealing contact with said pipe disposed interiorly of said section; and a clamping flange outwardly projecting from the lower portion of said second section, said clamping flange being disposed adjacent a horizontal surface beneath said floor; a clamping ring; means for securing said clamping ring juxtaposed to one side of said clamping flange; and a waterproof membrane clamped between said clamping ring and said clamping flange whereby a waterproof lining is formed between said floor and said horizontal surface
