Do it No-Seep No 3 Wax Ring Bowl Gasket is a urethane reinforced, extra thick gasket designed for superior durability and performance. It is up to 20 times stronger than ordinary wax gaskets and fits both 3" and 4" lines, accommodating most wall and all floor toilet bowls. This resilient gasket springs with bowl movement, ensuring a secure and lasting seal. Unlike fiber or sponge gaskets, it is permanent and will not rot over time. The No Seep sleeve protects the sealing area by extending the bowl into the waste line, providing three times the sealing power of plain gaskets. It also up to 1/2" tolerance in rough-in and bowl setting, making installation easier and more reliable. Model Number: 004410
