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 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 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 retrofit no filter no run insert for existing filtration systems manufactured without a no filter no run engine integrity protection feature. The insert is beneficial for a manufacturer that initially does not require the benefit of a no filter no run engine integrity protection feature but later requires such a feature. The insert can be installed into the existing filtration system without any modification to the existing filtration system head. The no filter no run insert prevents the equipment supplied by the filtration system (e.g., an internal combustion engine) from being operated without a filter element. Further, the no filter no run insert prevents the equipment supplied by the filtration system from being operated with an unauthorized or non-genuine replacement filter element. The no filter no run insert safeguards against damage to downstream components of the filtration system and malfunctions of equipment in which the filtration system is used.

A filter assembly includes a housing having an outer cavity and an inner cavity, and a gasket disposed within the housing. The gasket includes an inner surface, an outer surface, and a vent passage. The gasket forms a first seal with a central tube at the inner surface. The central tube extends into the inner cavity and includes an opening. A filter element is positioned within the housing and includes a filter media configured to filter a fluid and an endcap including an annular tab portion that forms a second seal with the outer surface of the gasket when the filter element is positioned in an operating position within the housing. The vent passage circumvents the first seal and the second seal, allowing air to flow from the inner cavity of the housing to the opening in the central tube.

Fuel filter cartridges with automated air-bleeding internal features

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.

A replacement filter element having a removable pin attached to the filter elements is described. The removable pin is attached to the filter element via a first interference fit. When the replacement filter element is installed into a filtration system having a drain valve with an internal draft, the removable pin seals onto the drain valve and forms a second interference fit between the drain valve and the pin. The pin seals an opening in the drain valve. The second interference fit is stronger than the first interference. Accordingly, when the replacement filter element is removed from the filter housing (e.g., during a service event of the replacement filter element), the pin detaches from the replacement filter element and remains positioned within the drain valve thereby preventing fluid from leaking from the housing when the filter element is removed. The pin permanently plugs the drain valve once installed.

Filter leak path prevention via interference pin

A heated filter shell assembly for a fuel filtration system includes a filter shell defining a cavity sized to accommodate at least a portion of a fluid filtration cartridge and a cartridge receiving aperture at a first end. A heating element is disposed within the cavity and is operatively coupled to the filter shell adjacent to a second end of the filter shell. A feed wire is operatively coupled to the heating element at a feed wire first end and is configured for electrical energy receiving communication with an energy source at a feed wire second end.

Filter shells with mounted heaters

A replacement filter element having a removable pin attached to the filter element is described. The removable pin is attached to the filter element via a first interference fit. When the replacement filter element is installed into a filtration system having a drain valve with an internal draft, the removable pin seals onto the drain valve and forms a second interference fit between the drain valve and the pin. The pin seals an opening in the drain valve. The second interference fit is stronger than the first interference. Accordingly, when the replacement filter element is removed from the filter housing (e.g., during a service event of the replacement filter element), the pin detaches from the replacement filter element and remains positioned within the drain valve thereby preventing fluid from leaking from the housing when the filter element is removed. The pin permanently plugs the drain valve once installed.
