Abstract: A closet flange for use in installation of a toilet in relation to a waste pipe. The closet flange comprises a body formed of polymeric material, the body including a tubular portion having a proximal end and a distal end and a flange portion located at the proximal end of the tubular portion. The flange portion extends radially outward with respect to the tubular portion of the body, the flange portion defining an inner periphery forming a drain opening aligned with an interior of the tubular portion and further defining an outer periphery. The flange portion also defines a plurality of fastener openings therethrough for use in securing the closet flange to a mounting surface. A seal membrane is removably attached to the flange portion so as to cover the drain opening in a water-tight manner.

Abstract: A mechanical coupling between a straight pipe end and a socket fitting comprises a seal ring and a locking ring disposed within the interior of the socket. The locking ring has a generally frustoconical shape with a plurality of corrugations extending circumferentially thereabout, the corrugations presenting inner edge portions engaging the outer annular surface of the pipe end and outer edge portions engaging the interior annular surface of the socket for opposing withdrawal of the pipe end axially outwardly from the socket.
