Perfect seal is an innovative new product that takes the guesswork out of toilet installation. It fits any drain size and flange depth. Whether your flange is above the floor or below the floor due to re-tiling, the perfect seal guarantees a perfect seal the first time, every time. The patented seal design combines specially designed rubber gaskets with encapsulated wax to form a seal that is three times stronger than a wax ring without the mess. Unlike wax rings, the perfect seal stabilizes toilet bolts and allows the toilet to be repositioned as needed.
