1. Package Contents: You will receive 1 toilet flange gasket suitable for sizes ranging from 100–110 mm, compatible with most household sewage outlets. Our odorresistant toilet rubber gasket provides sealing performance, effectively preventing odors from entering the bathroom, ensuring a clean and tidy environment for you and your family. (Note: Please verify the size before .) 2. Triple Odor Resistance, Tighter Seal: Our replacement toilet gasket features a 3layer antiodor design, effectively blocking and isolating odors. It uses polymer soft adhesive for bonding, fits closely to the toilet, and seals tightly to prevent wastewater leakage. The design sits flush with the floor, eliminating backflow odors, and incorporates multiple strength silicone gaskets to effectively seal gaps between the toilet, sewage outlet, and floor, reducing pipe odor emissions. 3. SelfClosing Valve Design for Better Odor Prevention: The bottom of our toilet flange gasket features a spring rebound and a 90° wideopening/closing design, automatically closing the valve, opening the drain when in use, and sealing when dry. This blocks and isolates odors, prevents sewage leakage, and ensures a tight fit between the drainpipe and gasket for odor control. 4. Strong Adhesion Easy Installation: Our thickened toilet flange gasket is easy to install. First, clean and keep the toilet base dry. Then, attach the toilet stopper to the drain outlet, stick the sealing strip to the bottom of the toilet, align the toilet with the floor drain outlet, peel off the selfadhesive porcelain insulation paper, and press firmly. 5. Quality Material: Our odorproof rubber drain gasket is made of strength, antiaging rubber material, resistant to aging and corrosion. It features strong adhesion, durability, and a long lifespan. It remains stable under seasonal temperature changes, resists cracking and aging, adapts well to temperature variations, and effectively prevents odor contamination.
