Main function: Seals the connection between the toilet fill valve and the water supply or internal fill components, providing a tight seal to prevent leaks, supporting proper operation and reducing water wastage. Precise design and installation: The precise design enables seamless installation and reliable performance. Material and durability: Made from rubber to withstand frequent use and maintain a stable seal over time. Noise reduction and efficiency: Effectively reduces water flow noise, improving tank efficiency and contributing to a durable, efficient toilet system. Compatibility and fit: Designed to seal connections between fill valves and the water supply or internal fill components; compatible with typical fittings found in many toilets. Use scenarios: 1) Residential bathroom maintenance: worn seals on the fill valve to stop slow leaks and conserve water. 2) installations or remodels: ensure a tight seal between water supply and fill valve for reliable operation. 3) usage environments: maintain consistent sealing with repeated fill cycles to reduce noise and extend toilet system life.
