Abstract of the Disclosure A self contained sealing arrangement for drains and pipe connections includes a sleeve-like, cylindrical sealing gasket having a plurality of annular ribs disposed on the inner and outer surfaces thereof and spaced longitudinally therealong. A pair of compression rings are disposed at opposed ends of the sealing gasket, each having annular surface portions adapted to impinge upon its respective end surface of the gasket. The end surfaces of the gasket are each provided with an annular surface portion adapted to cooperatively engage the confronting annular surface of the respective compression ring. A plurality of screw holes extend through one ring and also longitudinally through the sealing gasket, and are aligned with a like plurality of tapped holes in the other ring. A like plurality of screws extend through the first ring and the gasket and are secured in the tapped holes of the other ring. The gasket assembly is received about a pipe end disposed within a drain body or pipe connection, and is situa- ted in the annular space defined by the outer surface of the pipe end and the inner surface of the drain or pipe connection. The screws may be tightened in their respective tapped holes to compress the sealing gasket longitudinally, driving the annular surface portions together and causing radial expansion of the gasket inwardly and outwardly to effect a seal between the pipe and the drain or pipe connection.
