Abstract
Apparatus including an elastomeric gasket and a rigid holder therefor for resiliently connecting a sewer pipe in the wall opening of a concrete manhold to prevent leakage through the connection under extreme conditions of ground settling and overhead loading. The base of the gasket is anchored in the opening with its interior surface in flush alignment with diverging surfaces of the wall opening and having an inside diameter substantially corresponding to the outside diameter of the pipe for a press fit. The holder is preassembled with the gasket for casting of a port in a wall in situ.
