Abstract: A filter element assembly is disclosed which comprises a filtration media and an end fitting (154, 200) through which a sealing connection is made between the filter element assembly and a housing (100) so that, when the sealing connection is made, the end fitting (154, 200) defines in part a flow path for fluid between the housing (100) and the filtration media, in which the end fitting (154, 200) has first (200) and second (154) parts which can be separated axially, the filter media extending axially away from the second part (154) in a direction away from the first part (200), each of the first and second parts having an outer wall (204, 160) with an external cylindrical surface which is threaded (212, 158), and in which each of the first and second parts (200, 154) has an axially facing edge surface which faces the other of the first and second parts, the facing edge surfaces being shaped to define a pre-determined relative rotational alignment of the first and second parts (200, 154) in which the first and second parts fit together so that the threads (212, 158) on the external surfaces of the first and second parts (200, 154) form a continuous thread.

Abstract: A filter element (2) is disclosed which comprises a filtration media (4) and an end fitting (6) through which a sealing connection is made between the filter element and a housing (100) so that, when the sealing connection is made, the end fitting defines in part a flow path for fluid between the housing and the filter element. The end fitting includes an annular seal (36') made from a compressible material which extends around the periphery of the filter element, and a support (30, 31, 32, 34) for the annular seal which can be expanded outwardly to cause the transverse dimension of the seal to increase so that the seal is urged into contact with an inner wall of a housing (100) in which the filter element is located.
