Abstract: A filter element includes a first end cap, a second end cap, and a ring of filter media disposed between the first end cap and the second end cap. The ring of filter media circumscribes a central cavity. The filter element also includes an air-bleed conduit axially extending through the central cavity. The air-bleed conduit includes a first portion integrally formed with the first end cap and a second portion integrally formed with the second end cap. The second portion is configured to fluidly connect to the first portion.

Abstract: A sub-component of a replaceable filter element that is interfacably sealing a standpipe includes an end cap, said second end cap defining a first central opening; a central tube extending from the first central opening of the second end cap, wherein the central tube defines an inner surface, an outer surface and a top surface, wherein the top surface defines a second central opening, wherein the central tube includes an actuator excluding keys, free ends, or projections; and a standpipe seal disposed proximate the top surface of the central tube, wherein the standpipe seal defines a third central opening.

Abstract: One aspect of the disclosure provides a filter element including a first end cap, a second end cap, a ring of filter media and an annular seal. The first end cap defines a cylindrical collar that circumscribes a first central opening and includes a substantially planar first outer surface that extends radially outward from the cylindrical collar to an outer peripheral edge. The second end cap defines a second central opening substantially coaxial with the first central opening. The ring of filter media is disposed between the first end cap and the second end cap, and circumscribes a central cavity in fluid communication with the first central opening and the second central opening. The annular seal is disposed upon the first outer surface of the first end cap and around the cylindrical collar. The annular seal extends axially way from the first outer surface.

Abstract: An apparatus configured to engage a filter housing and an end of filter media includes an endcap and at least one biasing portion. The endcap includes a first axial surface, a second axial surface arranged opposite said first axial surface, and an outer radial surface transverse to the first and second axial surfaces. The first axial surface is configured to engage the end of the filter media. The at least one biasing portion includes a proximal end integrally formed with the endcap, and a distal end extending radially outward of the outer radial surface.

Abstract: 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.

Abstract: A spin-on filter includes a housing and a cover plate defining a central opening. The housing has a closed end a circumferential wall extending from the closed end to an open end and circumscribes an internal chamber configured to receive a filter element. The cover plate includes a substantially planar outer surface extending radially outward from the central opening to an outer circumferential wall. The spin-on filter also includes a series of engagement tabs integrally formed with one of the outer circumferential wall of the cover plate or the interior wall of the housing. Each engagement tab is configured to mate with corresponding ones of a series of receiving slots formed within the other one of the outer circumferential wall of the cover plate or the interior wall of the housing when the cover plate and the housing are axially pressed together to secure the cover plate to the open end of the housing.

Abstract: A filter is disclosed. The filter includes a sheet of filter media defining a body having an upper portion, a lower portion, a first end surface proximate the upper portion, a second end surface proximate the lower portion, and a first side surface extending between the first and second end surfaces. One or more of the upper and lower portions define a ledge, wherein the ledge defines a third end surface arranged between the first and second end surfaces, and a second side surface extending between the first and third end surfaces; and a seal disposed upon the ledge. A method for manufacturing the seal is also disclosed.

Abstract: An endcap bypass plug includes a body and a plurality of leg members. The body includes an upper surface, a lower surface, and an outer side surface joining the upper and lower surfaces. The plurality of leg members are connected to and extend away from the upper surface of the body. Adjacent leg members of the plurality of leg members are spaced apart by a distance to form a plurality of radial passages defining a plurality of radial fluid-flow paths. Each leg member includes a head portion having an upper surface. The head portion includes a nose portion extending radially outwardly from the head portion and including a ramp surface and a lower surface. The ramp surface of the nose portion is connected to the upper surface to define an upper edge. The ramp surface is connected to the lower surface of the nose portion to define a lower edge.

Abstract: An apparatus configured to engage a filter housing and an end of filter media includes an endcap and at least one biasing portion. The endcap includes a first axial surface, a second axial surface arranged opposite said first axial surface, and an outer radial surface transverse to the first and second axial surfaces. The first axial surface is configured to engage the end of the filter media. The at least one biasing portion includes a proximal end integrally formed with the endcap, and a distal end extending radially outward of the outer radial surface.

Abstract: An endcap bypass plug is disclosed. The endcap bypass plug includes a body and a plurality of leg members. The body includes an upper surface, a lower surface and an outer side surface joining the upper surface to the lower surface. A central axis extends through an axial center of the body. The plurality of leg members are connected to and extends away from the upper surface of the body. Adjacent leg members of the plurality of leg members are spaced apart by a distance to thereby form a plurality of radial passages defining a plurality of radial fluid-flow paths there between. Each leg member of the plurality of leg members includes: a head portion having an upper surface. The head portion includes a nose portion extending radially outwardly from the head portion. The nose portion includes a ramp surface and a lower surface. The ramp surface of the nose portion is connected to the upper surface of the head portion to define an upper edge.
