    Abstract: An in-line filter includes a hollow base having first and second wall portions formed between its ends and a filter element mounted on the base. During use, the base of the filter is disposed inside a standard tubing connector, and the wall portions are resiliently deformed by the tubing connector such that the surfaces of the wall portions are pressed into sealing contact with internal surfaces of the tubing connector. The filter element connected to the base is disposed inside the tubing connector and/or tubing to which the tubing connector is attached. According to another form of the invention, a filter element includes a hollow base having a radially outwardly extending flange. An annular sealing member is mounted on the flange, and a filter element is mounted on the base. During use, the base of the filter is disposed inside a standard tubing connector, and the sealing member is pressed into sealing contact with internal surfaces of the tubing connector and with the flange.

    Abstract: A filter for subterranean environments includes an inner support member capable of transporting a fluid in an axial direction thereof, a filter body disposed around the inner support member and including a filter medium, and one or more end connectors surrounding the inner support member and each connected to an end of the filter body. Each end connector has a structure such that it can be installed on an inner support member having lengthwise ends with an outer diameter larger than the inner diameter of the end connector. According to one form of the invention, an end connector comprises a plurality of arcuate sections which are combined to surround the inner support member and are immobilized with respect to each other. According to another form of the invention, an end connector comprises a split annulus having two circumferential ends. The annulus can be deformed between an expanded state in which the annulus can be fit over the inner support member and a closed state in which the annulus fits sufficiently closely around the inner support member to be sealed to it. According to another form of the invention, an end connector comprises concentric inner and outer sleeves.
