Abstract

Fluid filtration assemblies (10) include a generally cylindrical core element (20) which supports a filter membrane (36) (e.g., a microporous film preferably formed of polytetrafluoroethylene, PTFE) and is concentrically positioned in a rigid (e.g., stainless steel) tubular housing (12). The core element (20) is most preferably formed of a fluorocarbon polymer so as to be compatible with the PTFE microporous membrane film (36) wrapped around its cylindrical external periphery. The core element (20) itself includes annular spaced-apart support ribs (34) for the membrane film (36) and openings (40) through the core sidewall. Dual seal flanges (24, 26) are unitarily formed at one end of the core element. In use, the flanges (24, 26) will be press-fit into, and be permanently deformed by, the internal cylindrical surface of the rigid housing (12) thereby forming a tight fluid seal therebetween.
