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 without mechanical or chemical connection to the pleats. Preferably, the support layer has a strand angle between 60 and 90 degrees, and a strand density sufficient to mark the element with appropriate identification indicia. End caps are disposed at opposite ends of the fluid filter. The cylindrical filter media is radially compressed through a conical tool into the outer sleeve. An inner support core or mandrel with a second conical tool is then forced into the cylindrical filter media to enlarge the media such that the outer sleeve elastically stretches and conforms to the pleat peaks.
