<p>A self contained sealing arrangement for drains and pipe connections includes a rigid cylindrical sleeve and an annular sealing gasket adapted to be secured to one end of the sleeve. A compression ring is disposed adjacent to the one end of the sealing gasket, and is adapted to impinge upon its respective end surface of the gasket. The confronting surface of the gasket is provided with an annular groove adapted to cooperatively engage the confronting V-shaped end of the sleeve. A plurality of screw holes extend through the compression ring and also through the sealing gasket, and are aligned with a like plurality of tapped holes in the sleeve. A like plurality of screws extend through the compression ring and the gasket and are secured in the tapped holes of the sleeve. The gasket assembly is received about a pipe end disposed within a drain body or pipe connection, and is situated 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, causing radial expansion of the gasket inwardly and outwardly to effect a seal between the pipe and the drain or pipe connection. A seating ring may be secured about the other end of the sleeve to seat the sleeve properly in the plumbing fixture.</p> |
