This 3-pack of genuine Mansfield 630-0030 flush valve seals is designed specifically for Mansfield tower-style flush valves, including models 210 and 211. It also fits Mansfield Model 160 tanks, which use the 211 flush valve. These red seals are the only ones engineered to properly fit Mansfield tower flush valves and ridged-style flappers, ensuring reliable performance and a watertight seal. Measures approximately 3-1/2" outer diameter and 2-1/4" inner diameter for a secure, leak-free seal.
Over time, old seals can develop a ridge or cone shape, leading to toilet leaks or difficulty flushing. Replacing a worn seal with this genuine part is the most common and effective fix. Made from a durable, proprietary compound, these seals outlast standard silicone and generic alternatives by maintaining the perfect balance of softness and support required by the flush valve.
Important: Genuine Mansfield parts come sealed in official Mansfield-branded packaging. If your product arrives loose or repackaged, it is not an authentic Mansfield part.
