Preassembled check valve cartridges conveniently insert into a reusable housing and function in either the inlet or outlet position. The two-piece Free-Turnâ„ design allows the outside housing thread to spin independently of the tube fitting port so the housing can be removed from the pump head with the tubing attached. A single cartridge is interchangeable across multiple pump brands. Ceramic ball and seat sets are precision-matched to exacting standards. Conversion kits include the necessary check valves and cartridges to convert a system with OEM style check valves to the OPTI-MAXÂ cartridge check valve system.
