Abstract
A method for sealing a porous membrane constructed, at least in part, of a PTFE based material to a support gasket constructed, at least in part, of a PTFE based material. The method includes providing such a PTFE porous membrane of a preselected shape and size and providing such a PTFE support gasket of a preselected shape and size. The method further includes positioning the membrane and the support gasket in a predetermined appositional relationship within a press. The press includes a press tool of a predetermined configuration and size. The method then includes sealing the membrane and support gasket together at a common seal-zone by pressing the press tool against the membrane and the support gasket with the pressing means at a predetermined pressure for a predetermined dwell to form the membrane/gasket assembly. The method lastly includes removing the membrane/gasket from the pressing means. The disclosed method provides a membrane/gasket assembly that is durable, easily handled, easily installed and sealed within an apparatus. The method is able to be performed without applying heat or adhesives to effect the sealing of the resulting membrane/gasket assembly.
