4 Pack Red Silicone Toilet Fill Valve Diaphragm Replacement Fits for Korky 528 R528 QuietFILL Platinum & TOTO Fill Valves Leak Proof Quiet Water Seal Repair Parts

Feature:【Compatibility】Designed as a dedicated replacement part fits for Korky 528 and R528 fill valves, this product is a perfect fit for Korky's QuietFILL and Platinum series fill valves, and is also compatible with many mainstream TOTO toilet fill valve models.【Superior Materials】The fill valve diaphragm is crafted from high-elasticity, thickened rubber, offering exceptional toughness and excellent resistance to stretching, tearing, and fatigue. It is designed to withstand long-term water pressure cycles in toilet tanks and frequent opening and closing cycles, making it resistant to deformation, hardening, cracking, and flaking.【Strong Sealing Performance】With excellent elastic sealing properties, it precisely controls the opening and closing of the inlet valve to stop water flow, completely resolving common toilet inlet valve issues such as slow seepage, continuous dripping, abnormal tank water levels, and constant refilling. The seal is extremely stable, ensuring a tight, leak-free shut-off that effectively prevents water waste and eliminates problems like toilet leaks, unusual noises, and high water bills.【Quiet Operation】The flexible rubber diaphragm cushions the impact of incoming water pressure, effectively reducing water flow vibrations and noise. The filling process is smooth and gentle, with no piercing whistling sounds or high-frequency vibration noise. Nighttime refilling is quiet and won't disturb your sleep, making it perfectly suited for home bathrooms and bathrooms adjacent to bedrooms. It balances practicality for maintenance with a comfortable living experience, restoring the original quiet filling performance.【Stable Water Control】The diaphragm in the toilet fill valve cover responds sensitively, providing precise and stable water control. It quickly detects changes in the tank water level and accurately switches between filling and shutting off the water supply. This ensures rapid refilling while precisely maintaining water pressure, preventing filling failures caused by water pressure fluctuations. It guarantees the normal operation of the toilet's flushing and water storage functions, restoring the fixture to like-new condition.Specification:Name: Toilet Fill Valve Cap Diaphragm​Material: SiliconeSize: 35.12*2.57*8.45mm/1.38.0.10*0.333inColour: RedPackage Included:4 * Toilet Fill Valve Cap Diaphragms
