ABSTRACT:
In a filter with fluid connections, an upper housing part (1) and a lower housing part (8) a flat filter blank (7) is sealingly clamped in like a sandwich between their circular and circumferential opening edges (6) and flange parts (11) in such a manner between the interconnected housing parts (1,8) that fluid can penetrate from one housing part (1) into the other housing part (8) only through the selectively permeable flat filter blank (7). The one housing part comprises threads (5) on the cylindrical outer edge of its opening edge facing the flat filter blank (7) and the connection of both housing parts (1,8) consists of a sprayed-on plastic ring (12) which holds the two housing parts (1,8) with flat filter blank (7) in a sealing and clamping position, completely fills up the threads (5) of the one housing part (1) and extends over the edge (11) of the other housing part (8) like a detachable union nut, so that a detachable housing connection is formed and the flat filter blank (7) can be removed from the filter housing for further testing.
