A bidirectional gasket providing a water-tight seal between an opening in a manhole assembly and a pipe extending into said opening having a T-shaped anchoring portion for embedment in a manhole opening. An A-shaped pipe engagement portion is joined to the anchoring portion by a connecting web which facilitates bending of the gasket. The A-shaped portion has "legs" and recesses which form water pockets preventing water from entering into the manhole assembly between the gasket and the pipe. The durometer of the gasket enhances the water tight seal of the legs with increasing water pressure. The pipe engaging portion accommodates a greater outside pipe diameter compared with conventional connectors due to reduced volume, by providing voids within the connector. The gasket has the ability to accommodate diameter deflection or ovation in rigid and flexible pipe materials. The A-shaped profile provides greater angular deflection and/or pipe misalignment allowance compared with conventional connectors. Tapered projections near the apex thereof wipe the external periphery of a pipe upon insertion and further contribute to compression of the connector in the nose portion, while preventing the projection from flipping over during pipe insertion. The web joining the anchoring portion to the pipe engagement portion has a tapered cross section, increasing in thickness toward the pipe engagement portion enhancing compression of the web against the pipe. The connecting web and interior periphery of the T-shaped anchoring portion are provided with integral projections which eliminate profile thinning and significantly reduce water infiltration. The simplified water pocket recesses ease installation problems and prevent pull-in of the water pocket which results in a connector failure.
