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.
