PACKAGE LIST: You will receive 1 toilet flange sealing ring, size 125mm, suitable for most domestic drain sizes. Our anti-odor toilet sealing rings have good sealing performance, which can effectively prevent odors from entering the bathroom, ensuring a clean and tidy environment for you and your family. (Note: Please check the size before purchasing) TRIPLE ANTI-ODOR, MORE TIGHTLY SEALED: Our toilet flush seal features three anti-odor technologies, effectively blocking and isolating odors. Made of soft, high-polymer rubber, it tightly seals the toilet, preventing wastewater leaks. It sits close to the floor, preventing odors from returning. Multiple high-tenacity silicone seals effectively seal the gap between the toilet, the wastewater outlet, and the floor to prevent odors from escaping the drain. SELF-CLOSING VALVE DESIGN, BETTER ODOR PREVENTION: The bottom of our toilet rubber ring features a spring-loaded mechanism and a 90° opening and closing design. This automatically closes the valve, opening the drain automatically and closing it automatically when there is no water, effectively blocking odors and preventing leaks. When wastewater is present, the downpipe and sealing ring are tightly adhered to the floor, resulting in better odor prevention. GOOD ADHESION, EASY TO INSTALL: Our rubber toilet ring is easy to install. First, clean the toilet floor to ensure it is dry. Then, stick the toilet stopper onto the top of the toilet drain. The seal will adhere to the bottom of the toilet. Align the toilet with the floor drain, tear off the adhesive backing, and press firmly.
