J-hook filter assembly
A fluid filter assembly includes a housing, a proximal end cap, and a nut plate. The housing defines a longitudinal axis and includes an inner surface. The inner surface surrounds the longitudinal axis and defines a hook portion. The proximal end cap is disposed within the housing and includes a flange engaging the inner surface of the housing. The nut plate is disposed within the housing and includes a proximal end and a distal end. The proximal end engages the hook portion of the housing. The distal end engages the proximal end cap.
1. A method of manufacturing a fluid filter assembly, the method comprising:
providing a housing including an inner surface surrounding a longitudinal axis, the inner surface including a proximal portion defining a first diameter, a distal portion defining a second diameter, and an intermediate portion defining a third diameter that is less than the first diameter and greater than the second diameter;
engaging a proximal end cap with the intermediate portion of the inner surface of the housing;
engaging a nut plate with the proximal end cap; and
forming a hook portion of the housing to engage the nut plate and wedge the nut plate between the hook portion and the proximal end cap.
2. The method of claim 1 , wherein forming the hook portion of the housing includes crimping the housing to an axially-extending ring of the nut plate.
3. The method of claim 1 , further comprising:
inserting a filter element within the housing; and
engaging the proximal end cap with the filter element,
wherein engaging the proximal end cap with the filter element includes engaging a radially outwardly extending flange of the proximal end cap with the inner surface of the housing.
4. The method of claim 3 , wherein the flange includes a plurality of fluid openings circumferentially spaced about the longitudinal axis.
5. The method of claim 4 , wherein the fluid openings direct fluid toward the filter element.
6. The method of claim 3 , further comprising:
engaging a distal end cap with a distal end of the filter element, opposite the proximal end cap; and
engaging the distal end cap with the inner surface of the housing.
7. The method of claim 1 , wherein the hook portion defines a j-shaped construct.
8. The method of claim 1 , wherein the hook portion extends radially inwardly.
