The black, limescale-resistant NR rubber ball is a high-quality replacement component designed to ensure secure, long-lasting seals inside flush mechanisms and valves in sanitary systems. Made of black NR rubber (natural rubber), this ball features specific limescale-resistant properties that limit the accumulation of limescale deposits on its surface. This benefit is particularly valuable in hard-water areas, where limescale tends to quickly impair component operation. The ball is also chlorine-resistant, making it suitable for prolonged contact with treated drinking water and sanitizing products while maintaining its mechanical properties over time. As a sealing element, it ensures an airtight closure by exploiting the natural elasticity of the rubber, allowing it to adapt perfectly to the sealing seat and prevent dripping, leaks, and water waste. With a diameter of 57 mm and a larger 18 mm hole, this model is suitable for mechanisms requiring a larger housing, offering a reliable and economical solution for system maintenance. Its resistance to limescale and chlorine makes it superior to traditional balls, ensuring consistent performance even under demanding operating conditions. We recommend periodically checking the condition of the rubber and replacing it at the first signs of hardening or wear to maintain a perfect seal and avoid waste.
