Toilet flange seal deodorizing thickened and leak-proof base universal anti-backflow check valve

-Description- Diverse Materials, Excellent Performance- Rubber: Features excellent elasticity and flexibility, allowing it to fit snugly between the toilet drain outlet and the floor drain, effectively filling gaps and ensuring a secure seal. Rubber also offers excellent pressure resistance, abrasion resistance, and corrosion resistance, making it durable and adaptable to a variety of complex bathroom environments.- Silicone: Chemically stable, corrosion-resistant, and age-resistant. Some silicone toilet flange seals are non-toxic and odorless, making them safer and more environmentally friendly. Their smooth surface resists staining, making them easy to clean and providing excellent sealing performance, effectively preventing odor and wastewater leaks.- Compact Design, Powerful Functionality- Funnel-Shaped Design: Typically, the funnel-shaped structure features a top that fits snugly into the groove at the bottom of the toilet bowl, while the bottom fits securely onto the drain pipe opening. This design ensures a secure seal even under pressure fluctuations, such as during flushing, effectively preventing wastewater and odor leaks. - Odor-Proofing Shutoff Valve: The seal is equipped with an odor-proof shutoff valve at the bottom. When sewage flows through, the valve automatically opens and closes after the water has flowed through, providing 24-hour insect and odor prevention, effectively preventing sewer odors and pests from entering the home.- Easy Installation and Wide Compatibility- Simple Installation: Installation is extremely simple, requiring no specialized tools or complicated procedures. Simply clean the toilet bottom and the area around the floor drain outlet, align the flange seal with the drain outlet, press it into place, and then let the toilet's weight secure it. Some products also come with a highly viscous polymer sealant. Simply apply the sealant to the drain outlet and then lower the toilet into the pipe.- Universal Size: Designed with market versatility in mind, the standard toilet flange seal is compatible with a variety of toilets and sewer pipe sizes. It can accommodate sewer pipes with diameters ranging from 70 to 115 mm, meeting the needs of most households.
