A filter element assembly used to filter liquid-state process stream. The assembly includes first and second tubes. A ring is seated in one of the tubes. One or more filter elements extend from the ring into one of the tubes. The ring has a lip that extends beyond the outside of the tubes. Opposed open ends of the tube abut opposed surfaces of the ring lip. A seal surrounds the open ends of the tube and the ring lip. A clamp surrounds the seal. Liquid that flows between the ends of the tubes and the ring lip forces the seal against the clamp and the outer tubes to prevent the liquid from flowing beyond the seal.
