Add an extra layer of protection between the base of your toilet and drain piping with the Water-Tite Wax Closet Gasket. Made of 100% pure petroleum, this wax bowl ring provides a permanent seal that is impervious to vermin, odors, gases, and acids. Once installed, the gasket forms a watertight, gas-tight, and odor-tight seal between the toilet bowl and a 3- or 4-inch waste line. Choose from standard- or jumbo-size gaskets, some of which have a horn that extends the discharge opening to create a more positive seal and assure proper bowl alignment. Some models also come with closet bolts to replace old or rusted hardware.
