ABSTRACT:
A fluid filter includes a cylindrical pleated filter media disposed around a central perforated support core or self-supporting. An outer support sleeve comprising a extruded nylon, diamond-shaped mesh is stretched across the pleated media, and elastically conforms to the pleat peaks to structurally retain the pleats of the pleat peaks in fixed relation to one another. A bead of adhesive is then applied over the sleeve to fix the sleeve to the pleat peaks. End caps are disposed at opposite ends of the fluid filter.
