The filter cartridge assembly has a valve body having an interior flow passage, a filter across the interior flow passage, and a check valve assembly in the valve body. The filter removes particulates as small as 0.003 microns. A check valve element adjacent to a valve seat in the interior flow passage has a check valve poppet and a stem. The check valve poppet has a relatively narrow neck, and the check valve poppet is tapered inwardly from the outlet end toward the neck at an oblique angle relative to the longitudinal axis of the valve body that is substantially equal to the oblique angle of the annular valve seat.
