Abstract
An in-line filter includes a filter element sandwiched between two gaskets. A sealing portion is disposed between the gaskets to forming a seal around a periphery of the filter element. The filter can be disposed inside a standard type of tubing connector, and a seal can be formed between the gaskets and opposing sealing surfaces of the tubing connector. The gaskets may directly contact the sealing surfaces of the tubing connector, or sealing members may be disposed between the gaskets and the sealing surfaces.
