The invention relates to an end plate for filter material (10) for filtering a liquid, particularly a hydraulic oil, having a through opening (11) for filtered liquid, which is surrounded by a sealing ring (20) for a connecting piece, and a cover (12) for the filter material (10). The invention is characterized in that the sealing ring (20) delimits a free space (13) for accommodating an anti-rotation lock (14) of a switch (15) and/or a bypass valve (16) of a filter system (30). Furthermore, the invention relates to a filter element, a filter system and a method for filtering liquid.

An upper plate provided on upper ends of a filtration member and an inner tube includes a tubular portion along the inner tube, a rib formed so as to protrude inward in a radial direction from an inner circumference of the tubular portion, and a hole formed in the rib. A gripping member has a protrusion portion that protrudes downward from a body portion having a thick plate shape inserted into a hollow portion of the tubular portion. When the gripping member is mounted on the upper plate, the protrusion portion is inserted into the hole.

A system for further filtering a liquid extract material after an initial extraction process. In an embodiment, the system includes a semi-rigid filter cup that is substantially cylindrical, the filter cup having a top and a bottom, wherein the top is oriented to receive filter media prior to a filtration process, and material to be filtered during the filtration process. The filter cup includes an integrated deformable flange at the top of the filter cup, an integrated top o-ring that is integrated into the top of the integrated deformable flange and an integrated bottom o-ring that is integrated into the bottom of the integrated deformable flange.
