KEROX K35B 35mm Mixer Tap Cartridge Replacement. Please note that the cartridge you will receive does not have the grey restrictor on it. If your K35B has a grey restrictor on the top, the new version without the restrictor will work for you as it does not affect the compatibility of the cartridge. Product: Tap Cartridge Installation: Push Fit Material: Alumina Ceramic The KEROX K-35B cartridge is suitable for, but not limited to, taps from: - Cascade - La Torre - Kohler Al2O3 Ceramic Disc Cartridge Al2O3 is the chemical formula for aluminium oxide, a compound of aluminium and oxygen. Sintered by heat into ceramic, cartridges made from the material are considered durable with a compressive strength of at least 2,000 megapascals (MPa) and are said to have almost the same toughness as a diamond with a hardness of up to 19 gigapascals (GPa). It is less prone to corrosion and can last longer than cartridges made from other materials. Another characteristic of alumina ceramic is its ability to slide, which is practical for a ceramic disc tap. Two discs are used in such a tap mechanism. The upper disc moves when the tap is turned on and off while the lower disc remains static. The discs slide to align or misalign, which acts as a gate to open or impede the flow of water.
