Behind this success are CeramTec’s carefully selected ceramics, optimized and proven through years of use, which uncompromisingly meet the demands of sanitary fittings in terms of the sealing power of the discs, hardness and reliability for single-handle mixers and mixing cartridges.
Ceramic seal discs, regulator discs and diverters are manufactured from alumina ceramics using a state-of-the-art method, which results in sliding surfaces with extraordinary, diamond-like hardness. They also offer outstanding chemical resistance against acids and alkaline solutions. These sliding surface properties ensure the superior reliability and long service life of Ceramdisc® seal and regulator discs. Solids carried in drinking water such as sand, rust, and lime are ground between the sliding surfaces of the ceramic discs without impacting the sealing power of the sanitary fittings. And this performance lasts to ensure exceptionally long service life. Even after millions of motion cycles they show no signs of wear and continue to precisely control the desired amount and temperature of the water in sanitary fittings – despite tough conditions such as fluctuating pressure ratios and water temperatures in the supply system.
