We claim the ornamental design for a cylindrical filter element, as shown and described. |
|||||||||||||||||
FIG. 1 is a front elevational view of a cylindrical filter element showing our new design;
FIG. 2 is a right side elevational view thereof; and,
FIG. 3 is a rear elevational view thereof.
The broken line showing of environmental structure in FIGS. 1-3 is for illustrative purposes only and forms no part of the claimed design.
A characteristic feature of the design resides in non-contnuous beads which are visible through a spiral wrap.
