Abstract

A filter subassembly is disclosed. The filter subassembly includes an end cap connected to a ring of memory material. The end cap includes a tube-shaped body, a first ring-shaped body, a second ring-shaped body and a third ring-shaped body. The tube-shaped body is defined by an inner radial surface, an outer radial surface, a first axial surface and a second axial surface. The inner radial surface defines a passage extending through the tube-shaped body. The first ring-shaped body extends axially away from the first axial surface of the tube-shaped in a first axial direction. The second ring-shaped body extends axially away from a second axial surface of the tube-shaped body in a second axial direction that is opposite the first axial direction. The third ring-shaped body extends axially away from the second axial surface of the tube-shaped body in the second axial direction that is opposite the first axial direction. Each of the first ring-shaped body, the second ring-shaped body and the third ring-shaped body are defined by an inner radial surface, an outer radial surface and an axial surface that connects the inner radial surface to the outer radial surface. One or both of the first axial surface of the tube-shaped body and the inner radial surface of the first ring-shaped body is disposed adjacent the ring of memory material. The second axial surface of the tube-shaped body, the inner radial surface of the second ring-shaped body and the outer radial surface of the third ring-shaped body collectively define a ring-shaped filter media receiving channel. A filer assembly is also disclosed. An assembly is also disclosed. A filter is also disclosed. A method is also disclosed.
