The invention relates to a cartridge (1) for a water fitting having a stationary bearing disk (2) on which a rotatable ceramic control disk (3) is placed and on which control disk (3) a sliding disk (4) made in particular of plastics material is located.
In order that no leaking water can escape from the cartridge (1) even at high water pressure, it is proposed that the control disk (3) is pressed against the stationary bearing disk (2) by a pressure element.
