摘要： A filter cartridge for purifying fluids such as water and chemicals is provided with sealing rings integrally formed with and extending circumferentially from a tube connected to the housing of the filter cartridge and intended to be inserted into a receptacle for providing or receiving fluids. The rings are elastic and compress when the filter cartridge is inserted into the receptacle, thereby providing a seal between the filter cartridge and the receptacle.

摘要： A filter cartridge containing resin beads for purifying fluids such as water and chemicals has a cylindrical housing with an interior compartment containing a fixed septum and a moveable piston-like septum. The resin beads are packed between the fixed septum and the moveable septum. The moveable septum is displaced upstream to account for expansion of the resin beads while the flow of the fluid through the filter cartridge causes the upstream septum to maintain a packing pressure on the resin beads. The downstream fixed septum will preferably have a cone-like shape.
