A filter element () is disclosed which comprises a filtration media () and an end fitting () through which a sealing connection is made between the filter element and a housing () 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 (') made from a compressible material which extends around the periphery of the filter element, and a support () 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 () in which the filter element is located.

Filter element

A filter element assembly comprises a filtration media and an end fitting through which a sealing connection is made between the assembly and a housing so that the end fitting defines a flow path between the housing and the filtration media. The end fitting has first and second parts which can be separated axially, and the filter media extends axially away from the second part in a direction away from the first part. Each of the parts has an outer wall with an external threaded cylindrical surface, and each of the first and second parts has an axially facing edge surface which faces the other of the first and second parts, the facing edge surfaces shaped to define a pre-determined relative rotational alignment of the first and second parts, where the parts fit together so that the threads on the external surfaces of the parts form a continuous thread.

Filter element assembly

A valve () comprising a housing (), a valve filter media () and an actuator (). The housing () defines a chamber () having an inlet () and outlet (). The media () is positioned within the chamber () such that liquids flowing between the inlet () and outlet () pass through the media (). The valve filter media () is formed of a material which can absorb hydrocarbons, causing the media () to change its material properties thereby restricting the flow of liquids through the valve () and increasing the pressure differential across the media (). The actuator () has at least a portion positioned within the housing chamber (). If the pressure differential across the media () exceeds a predetermined threshold, the media () bears against the actuator () causing the actuator () to restrict the flow of liquids through the valve ().
