A ringlike shaped resuable gasket of rubberlike material such as polyvinyl chloride capable of returning to its original shape for sealing the joint between a drainage pipe and a toilet bowl seals the toilet bowl horn at a central aperture sealing portion shaped to flexibly engage the horn to replace conventionally used wax sealing rings and the like. It may be installed in hot or cold weather conditions and resued when the toilet bowl is removed and replaced. A thin web portion integrally extending from the central sealing portion mates between the mounting flange surface and toilet bowl to supplement the central sealing surface, and preferably has offset tapered concentric ridges on both sides. A downwardly extending outer rim engages the flange for holding in place frictionally. Mating bolt apertures smaller than the bolts hold the bolts in place fully extended for mounting the toilet bowl.
A gasket for sealing the joint between a drainage pipe and a toilet bowl in a coupling of the type wherein the horn of a toilet bowl positioned on a floor surface by bolting its base to a mounting flange fitting connected with a drainpipe terminating at or below the floor surface to prevent leakage of gas or fluids through the coupling joint, comprising in combination, an integral gasket ring of rubberlike elastic material having a memory so that it returns to its original shape after flexing presenting a central aperture sealing portion shaped to flexibly seat against the horn of said toilet bowl with a thin sheet-like ring web portion extending laterally therefrom for fitting between the mounting flange and the toilet bowl defining integrally thereon at least two concentric raised ridges staggered on each side of the web along the web and tapered from the web portion outwardly to form wedges of substantially right triangular form for providing a liquid and gas retaining sealing joint supplementing the central aperture seal against the horn and an outer rim formed concentrically about the central aperture which extends downward in installed position to mate with the outer circumference of said flange and hold the gasket frictionally in place seated to receive the horn of the toilet into the central aperture sealing portion.
