These elements are enclosed in an external cuff turned on the end of the filter bag. The cap includes a radially extended rim having an external diameter greater than the inside diameter of the wire ring. The cap outer diameter is less than the inside diameter of the wire ring but exceeds the unstressed inside diameter of the expandable member.
