A bell and spigot coupling system is provided for joining corrugated plastic pipe which improves the coupling's sealing capability with increasing hydrostatic pressure, and causes a substantial component of the force generated therefrom to be absorbed axially through the coupled sections of adjoining pipe. The spigot end of one pipe which is received within a bell coupler for an adjoining pipe terminates in a small annular bed-forming rib which forms a gasket bed that holds a gasket compressed against a radially extending gasket sealing surface of the bell coupler.
