Abstract
A sub-assembly of a filter assembly is disclosed. The sub-assembly includes an endcap having a substantially cylindrical sidewall including an exterior surface and an interior surface and a housing having a substantially cylindrical sidewall including an exterior surface and an interior surface. The exterior surface forms at least one exterior recessed region. A portion of a length of the substantially cylindrical sidewall of the housing is deformed such that a portion of the interior surface of the substantially cylindrical sidewall of the housing is arranged at least partially within the at least one exterior recessed region formed by the exterior surface of the substantially cylindrical sidewall of the endcap for mechanically-coupling the housing to the endcap. A method is also disclosed.

A sub-assembly of a filter assembly, comprising:
- an endcap having a substantially cylindrical sidewall including an exterior surface and an interior surface, wherein the exterior surface forms at least one exterior recessed region;
- and
- a housing having a substantially cylindrical sidewall including an exterior surface and an interior surface, wherein a portion of a length of the substantially cylindrical sidewall of the housing is deformed such that a portion of the interior surface of the substantially cylindrical sidewall of the housing is arranged at least partially within the at least one exterior recessed region formed by the exterior surface of the substantially cylindrical sidewall of the endcap for mechanically-coupling the housing to the endcap.
A method for assembling a filter assembly, comprising the steps of:
- providing an endcap including a substantially cylindrical sidewall including an exterior surface and an interior surface, wherein the exterior surface forms at least one exterior recessed region;
- providing a housing including a substantially cylindrical sidewall including an exterior surface and an interior surface;
- arranging the exterior surface of substantially cylindrical sidewall of the endcap substantially adjacent the interior surface of the substantially cylindrical sidewall of the housing;
- deforming a portion of a length of the substantially cylindrical sidewall of the housing such that a portion of the interior surface of the substantially cylindrical sidewall of the housing is arranged at least partially within the at least one exterior recessed region formed by the exterior surface of the substantially cylindrical sidewall of the endcap for
- mechanically-coupling the housing to the endcap.
A method for assembling a filter assembly, comprising the steps of:
- providing a housing including a substantially cylindrical sidewall including an exterior surface and an interior surface, wherein the housing is formed from a blank of material by:
- deforming the blank of material in order to form an inwardly-projecting bead along a portion of a length of the blank of material,
- shaping the blank of material from a first, substantially planar geometry to a second, substantially tubular geometry such that opposing ends of the blank of material are arranged adjacent one another thereby forming a seam along a length of the blank of material, and
- joining the opposing ends of the blank of material;
- providing an endcap including a substantially cylindrical sidewall including an exterior surface and an interior surface, wherein the exterior surface forms at least one exterior recessed region;
- and
- arranging the exterior surface of substantially cylindrical sidewall of the endcap substantially adjacent the interior surface of the substantially cylindrical sidewall of the housing such that the inwardly-projecting bead along a portion of a length of the blank of material of the housing is registered within the at least one exterior recessed region of the endcap for
- mechanically-coupling the housing to the endcap.
