Abstract
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.
