The lever handle of the tap is connected to the discs by a shaft – GROHE uses solid brass for strength and durability. As the discs move over each other, they either block the water or allow it to pass through. Therefore the quality and machining of these parts will affect the performance of the your tap.
GROHE is one of the world’s leading tap manufacturers and one of the few that manufacture their own cartridges. Our cartridges are manufactured in a high-tech process and feature discs made from a space-proven ceramic alloy. The polished mirror-like surface of the discs is then coated with a special Teflon lubricant for frictionless operation. And because our taps are designed withstand years of use, we incorporate micro-chambers of this lubricant within the cartridge – for a lifetime of maintenancefree operation.
