“Two piece” toilets have a toilet tank outlet valve that links the tank water with a bowl. A nut and gasket structure are provided to provide an essentially ball and socket type joint between the tank and bowl to permit correction for out of plumb conditions without significantly compromising seal integrity. The gasket has an outward lower curvature and is supported from the inside by the nut. Preferably the lower end of the nut is cut away or curved such that in some configurations the gasket can flex inwardly, while being otherwise supported by the nut.
