A liquid filtering device includes a vessel and a filtering cartridge within the vessel. A pressure seal between the outlet venting of the cartridge includes a circumferentially extending skirt which is communicated with pressure at the inlet of the vessel, which is higher than the pressure of the outlet of the vessel by the pressure drop across the filtering cartridge. Accordingly, the skirt is maintained in sealing engagement with a portion of the vessel or the support plate area by the vessel, thereby preventing bypass of fluid directly from the inlet to the outlet.
