A filter assembly comprising a housing with a first coupling member formed in a housing first end of the housing. The filter assembly further comprises a filter head with a first thread formed on a surface thereof. The filter assembly further comprises an adapter. The adapter includes a first adapter end, a second adapter end, and an annular portion. The annular portion is disposed between the first adapter end and the second adapter end. A first axial wall extends from the annular portion axially towards the first adapter end. The first axial wall includes a third coupling member configured to engage the second coupling member on the filter head. A second axial wall extends from the annular portion axially towards the second adapter end. The second axial wall includes a fourth coupling member configured to engage a first coupling member on the housing.

Multiple threaded connector for filter

A liquid filtration system includes a filter head, a shell housing, and a filter cartridge. The filter head includes a skirt having a ramp disposed at a first end of the skirt. The shell housing is coupled to the filter head. The filter cartridge is disposed within the shell housing. The filter cartridge includes a filter media pack and am endcap coupled to a first end of the filter media pack. The endcap includes an interface member extending from an upper surface of the endcap. The interface member includes a scaling member that is at least partially tilted at an oblique angle relative to a central axis of the endcap. The scaling member is sealingly engaged with the skirt.

Filtration element with gradient seal interface

A filter cartridge endplate () is described herein that has a integrated flow structure. For example, the integrated flow structure has concentric flow portions disposed at a center of the endplate (), where a separator () is built into the endplate () the separates fluid flow. The endplate () includes a plate with a major surface, a separator () that protrudes axially away from the major surface. The separator () includes a first flow portion () and a second flow portion (), where the first flow portion () is disposed radially inward relative to the second flow portion (). The first flow portion () includes a channel () and the second flow portion includes a channel (). The respective channels () ae configured to allow axial fluid flow relative to the plate, and configured to allow fluid flow that is localized toward the center of the plate ().

Filter cartridge endplate with integrated flow structure

A no filter no filter no run attachment is disclosed. A shell defines a fluid passage from an upstream fluid aperture at a first end for fluid receiving communication with a filtration cartridge to a downstream fluid aperture at a corresponding second end sized and shaped for coupling to a fluid pump inlet. The shell further defines a pin aperture at the first end sized to receive a pin from the filtration cartridge. A divider segments the fluid passage into an upstream portion that comprises the upstream fluid aperture and the pin aperture and a downstream portion that comprises the downstream fluid aperture. The divider also defines an internal aperture that allows fluid communication between the upstream portion and the downstream portion. A ball is disposed in the upstream portion in fluid flow receiving communication with the upstream fluid aperture, and is sized to have a greater diameter than the internal aperture.

Retrofittable no filter no run filtration system

A filter assembly that comprises a housing, an outer filter element, and an inner filter element. The outer filter element is positionable within the housing and comprises an outer filter media. The inner filter element is positionable within the outer filter element and comprises an inner filter media, a media support structure, an inner top endplate, and an inner bottom endplate. The inner top endplate comprising a top rib that extends continuously around a portion of a top surface of the inner top endplate.

Filter assembly with an inner filter element with a top rib

A filter assembly includes a drain port comprising a top portion and at least one surface modification along the top portion. The drain port defines an aperture therein and is alignable with an outlet port. The outlet port includes a seal member that is attachable to an end portion of the outlet port. A portion of the aperture of the drain port is sealable to the seal member when the drain port and the outlet port are aligned such that the at least one surface modification of the drain port does not abut the seal member of the outlet port, thereby creating a sealed connection between the drain port and the outlet port.

Filter port seal

A filter assembly including a filter housing having a longitudinal axis, the filter housing divided into a first filter chamber and a second filter chamber. The filter assembly further includes a first filter element and a second filter element. The first filter element includes a first element top endplate, a first element bottom endplate, and a first filter media positioned between the first element top endplate and the first element bottom endplate. The second filter element includes a second element top endplate, a second element bottom endplate, and a second filter media positioned between the second element top endplate and the second element bottom endplate. The filter assembly further includes a solid tube positioned between the first element top endplate and the second element bottom endplate.

Chambered parallel flow dual filter

A no filter no run bidirectional pin element is disclosed. A shell housing is removably coupled to a filtration housing, a removable no filter no run attachment, and a filter element. The filter element comprises a filtration media and a bidirectional pin element. The bidirectional pin element comprises a center tube formed as a single piece with a bidirectional pin. The installation of the filter element and the shell housing into the filtration system results in the bidirectional pin entering a pin aperture of the removable no filter no run attachment and the bidirectional pin preventing the operative engagement of a blocking element with a divider inside the no filter no run attachment.

Bi-directional no filter no run pin

A no filter no filter no nm attachment is disclosed. A shell defines a fluid passage from an upstream fluid aperture at a first end for fluid receiving communication with a filtration cartridge to a downstream fluid aperture at a corresponding second end sized and shaped for coupling to a fluid pump inlet. The shell further defines a pin aperture at the first end sized to receive a pin from the filtration cartridge. A divider segments the fluid passage into an upstream portion that comprises the upstream fluid aperture and the pin aperture and a downstream portion that comprises the downstream fluid aperture. The divider also defines an internal aperture that allows fluid communication between the upstream portion and the downstream portion. A ball is disposed in the upstream portion in fluid flow receiving communication with the upstream fluid aperture, and is sized to have a greater diameter than the internal aperture.

For example, the integrated flow structure has concentric flow portions disposed at a center of the endplate (), where a separator () is built into the endplate () that separates fluid flow. The endplate () includes a plate with a major surface, it separator () that protrudes axially away from the major surface.

The first flow portion () includes a channel () and the second flow portion includes a channel (). The respective channels () are configured to allow axial fluid flow relative to the plate, and configured to allow fluid flow that is localized toward the center of the plate ().

A filter apparatus is described that has a torque limiting device, which may be a clutch mechanism, and which provides a protective function for a filter, so as to protect a filter from being over tightened and to thereby prevent damage to filter components. The clutch mechanism can also eliminate or reduce the need for torque measurement of certain filter components. The clutch mechanism can be located on one of the fluid filter, a filter head which engages the fluid filter, or a combination of both the fluid filter and the filter head.
