<p>APPARATUS WITH CUP SEALS Permeators having hollow fiber membranes suitable for fluid separations embedded in a tube sheet, where the tube sheet is positioned in a fluid tight relationship within the permeator by a cup seal. The cup seal comprises a polymeric ring which substantially surrounds and cooperates with a resilient member to provide both a pressure-actuated and self-actuated fluid tight seal.</p> |
