Abstract: A sealing member to seal the opening in the side wall of a chamber such as a catch basin through which a laterally extending member such as a drain pipe is positioned and connected. The sealing gasket comprises an annular ring having a cylindrical bore to receive such drain pipe for example, an annular groove cut into the annular ring which divides the portions adjacent the groove into a first annual flange on one side of the groove and a second annular flange on the opposite side of the groove. The sealing gasket is made of a flexible compressible material. It is worked into the opening to be sealed by flexing the gasket in such a way as to insert the peripheral edge of the wall surrounding the opening into the annular groove, whereupon one of the annular flanges is in sealing bearing relationship against the outer surface of the wall around the opening and the other annular flange is in sealing bearing relationship against the inner surface thereof.
