Abstract: A coupling for connecting one or more pipes or conduits. The coupling includes at least one wedge-shaped gasket extending around the coupling. The wedge-shaped gasket includes an outer sloped or inclined surface, an inner surface, and a pair of opposed ends where one end is higher than the other. In use, a pipe, duct or conduit is inserted over one end portion of the coupling such that as the pipe or conduit is moved or slipped over the wedge-shaped gasket, the gasket compresses and forms a seal between the coupling and a portion of the inner surface of the pipe or conduit.
