A wax-less toilet gasket is provided that is formed of an open cell foam having a hydrophobic skin, layer, coating or covering. To this end, the toilet gasket may be formed of a self-skinning polyurethane, a polyurethane with an in-mold coating, or a polyurethane with a waterproof agent. The toilet gasket is characterized by a body with a ring shaped upper portion and a truncated conical extension integrally extending downwardly therefrom. In use, fastening bolts that project through the toilet flange attached to the floor conduit then extend through the ring shaped configuration and attach to the toilet base.

1. A toilet gasket providing a liquid and gas seal between a lower surface of a toilet base and an upper surface of a toilet flange provided on a drain conduit to which the toilet base is mountable and through which liquid and gas waste flows, the toilet gasket comprising: a repositionable, ring-shaped body having a planar lower surface for contacting the upper surface of the toilet flange and an uninterrupted arcuate upper surface for contacting the lower surface of the toilet base, the repositionable, ring-shaped body of a flexible open-cell foam with a high yield for compression of a distance between the lower surface of the toilet base and the upper surface of the toilet flange and deflection of the distance between the lower surface of the toilet base and the upper surface of the toilet flange to maintain a seal against liquid and gas egress between the lower surface of the toilet base and the upper surface of the toilet flange while resiliently attempting to return to its original shape to accept movement between the body, the toilet base and the toilet flange, the open-cell foam body comprising a combination of polyether polyols, isocyanates, surfactants, chain extenders, catalysts and any single one of a combination of physical and/or chemical blowing agents and wherein BHT is present in the polyether polyol providing an anti-microbial construction; anda layer on an entire outer surface of the repositionable, ring-shaped body having a molded density between 0.04 and 0.40 gm/cc that is impermeable to liquid and gas waste and able to accept sealants bonded to the surface of all elements without compromising sealing. 2. The toilet gasket of claim 1, wherein the repositionable, ring-shaped body includes first and second holes each extending through the repositionable, ring-shaped body from the upper surface to the lower surface thereof and configured to receive a bolt securing the toilet base and toilet flange together with the repositionable, ring-shaped body therebetween. 3. The toilet gasket of claim 1, wherein the repositionable, ring-shaped body further includes a truncated cone extending from the lower surface of the repositionable, ring-shaped body and defining a hollow forming a liquid and gas passage and having an outside continuous surface of an outside diameter and an inside continuous surface of an inside diameter both of which decrease in diameter as the truncated cone projects downwardly, the inside continuous surface blending with the arcuate upper surface of the repositionable, ring-shaped body while the outside continuous surface joins with the lower planar surface of the repositionable, ring-shaped body at an oblique angle allowing for stacking of a second toilet gasket having the same limitations of this claim thereon wherein the truncated cone fits down into a truncated cone of the second toilet gasket such that the truncated cone keeps the toilet gaskets in place allowing them to compress in their own footprint. 4. The toilet gasket of claim 1, wherein the flexible open-cell foam core of the body allows the toilet gasket to function in hot and cold environments. 5. The toilet gasket of claim 1, wherein the layer comprises a polychloroprene, vinyl, PVC or any combination thereof.
