The 2-inch universal toilet flap is compatible with most standard US toilet water tanks and other 2-inch flush valves. It is an ideal replacement for old, leaking flappers and effectively resolves issues such as hissing sounds and water leakage. Please verify that your flush valve measures 2 inches in diameter before purchasing. Toilet flappers are constructed from high-quality PVC material, offering excellent sealing performance to prevent leaks. PVC is more resistant to aging compared to standard rubber materials. The design ensures a secure fit and significantly improves flushing performance. Stainless steel chains and hooks are included for durability and resistance to rust, making them reliable long-term components. The new flapper is easy to install and can be directly attached to the plastic flush valve. The chain with hook allows for adjustable length, and the included white buoy provides clear water level visibility. No professional plumber is required to fix a leaking toilet—this solution allows for quick, DIY repair. Package includes: 2 x 2-inch toilet flapper valves with hinges, 2 x 50mm white plastic buoy chains. Having two sets of replacement parts ensures you’re always prepared for maintenance without needing immediate store visits.
