This assembly includes: cartridge and housing. If you have not used ASI check valves in the past, then we recommend that you purchase the complete assembly. For better performance, we recommend that you use ASI check valves for both inlet and outlet. Non spring loaded Check Valve.

This check valve is suitable for all applications, however because the housing is made of Stainless Steel, the pumps should not be left idle for an extended period of time with halide containing buffers.  Rinse pumps with an alternative halide-free buffer or with pure water.
