This RELIABILT reinforced, jumbo wax ring, is constructed of a high-quality, premium wax that will not dry out or harden over time. Featuring 40% more wax than a standard ring, this eliminates double-stacking when just one ring is not enough. This wax ring features a polyethylene sleeve to ensure proper placement and seal between the flange and toilet bowl. This wax ring provides a watertight seal, preventing any seeping. Rest easy with high quality RELIABILT products.
