Abstract
A filter assembly comprises a housing defining an internal volume. An opening is defined at a bottom end of the housing. An adaptor is coupled to the bottom end of the housing. A filter element is disposed within the housing. The filter element comprises a filter media defining a central channel, and an endcap coupled to a filter media bottom end of the filter media proximate to the adaptor. A sealing member is disposed around the adaptor, the sealing member configured to form an axial seal between the endcap and the housing.

A filter assembly, comprising:
- a housing defining an internal volume, an opening defined at a bottom end of the housing;
- an adaptor coupled to the bottom end of the housing;
- a filter element disposed within the housing, the filter element comprising:
- a filter media defining a central channel, and
- an endcap coupled to a filter media bottom end of the filter media proximate to the adaptor;
- and
- a sealing member disposed around the adaptor, the sealing member configured to form an axial seal with the endcap and the housing, the sealing member including a sealing member surface abutting the endcap, thereby forming an axial seal with the endcap.
A filter assembly comprising:
- a housing defining an internal volume, an opening defined at a bottom end of the housing;
- an adaptor coupled to the bottom end of the housing;
- a filter element disposed within the housing, the filter element comprising:
- a filter media defining a central channel, and
- an endcap coupled to a filter media bottom end of the filter media proximate to the adaptor;
- a sealing member disposed around the adaptor, the sealing member configured to form an axial seal with the endcap and the housing;
- a nutplate coupled to a top end of the housing, the nutplate defining a central opening to allow fluid to flow therethrough;
- and
- a second sealing member disposed between the second endcap and the nutplate, the second sealing member providing a seal between the central channel of the filter element and the central opening of the nutplate.
A housing assembly for a filter element, comprising:
- a housing defining an internal volume for receiving a filter element that comprises a filter media defining a central channel and an endcap coupled to a filter media bottom end of the filter media, an opening defined at a bottom end of the housing;
- an adaptor coupled to the bottom end of the housing;
- and
- a sealing member disposed around the adaptor, the sealing member configured to form an axial seal with the endcap and the housing when the filter element is disposed in the housing, the sealing member including a sealing member surface configured to abut the endcap, thereby forming an axial seal with the endcap.
