The present invention relates to a filtering assembly (1) for filtering at least one fluid circulating in particular in an engine or a hydraulic device, comprising: a filter body (2), which comprises a vessel (3) and a head (4), the vessel (3) and the head (4) being provided to engage with one another in order to close the filter body (2), in particular by screwing; a tube (15), in particular a central tube, which is inside the filter body (2) and extends along a longitudinal axis (X); a removable filtration cartridge (16,) which is accommodated in the filter body (2) and includes an upper end plate (20), a lower end plate (21) and a filtration medium (22) which extends between the upper (20) and lower (21) end plates, the filtering medium (22) having a tubular opening (17) for surrounding the tube (15), characterized in that the upper end plate (20) comprises first reversible rigid-connection means (25) and in that the vessel (3) comprises second reversible rigid-connection means (26) which are complementary to the first reversible rigid-connection means (25), such as to enable the filtration cartridge (16) to stay in position in the vessel on the one hand, and in the filtering assembly (1) on the other hand, only by rigidly connecting the first and second reversible rigid-connection means (25, 26).

An integrated seal member includes an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction. The at least partially annular body includes a top annular mounting portion, a sealing portion including at least one top sealing feature and at least one bottom sealing feature, and a connecting portion that extends at least radially outwardly from the top annular mounting portion to the sealing portion.

A filter assembly that includes a filter housing with a housing interlocking feature, a filter cover with a filter cover interlocking feature, and a filter element with a filter element interlocking feature is disclosed. The filter element is positionable within the filter housing, and the filter cover is attachable to a top portion of at least one of the filter element and the filter housing. The housing interlocking feature, the filter cover interlocking feature, and the filter element interlocking feature are interlockable with each other and extend in a nonplanar configuration along at least one side of the filter element when the filter housing, the filter cover, and the filter element are assembled together.

A modular filter manifold includes one or more plates, each plate including connections for one or more filters on a first side, and connections for fluid lines on a second side opposite the first. At least two fluid line connections are provided for each filter connection, with a fluid passage through the plate for each fluid line connection. Each of the fluid passages are independent of one another. The manifold plates can be joined to a support structure to form a manifold to which filters can be attached. Piping can be connected to the fluid line connections to allow flow through the filters in series or parallel flow.

A filter assembly includes a body of filter media, a seal, and a compression ring. The body of filter media having a first end surface, a second end surface spaced apart from and opposing the first end surface, and an outer surface extending between the first end surface and the second end surface. The seal surrounds the first end surface. The compression ring is disposed about the second end surface. The compression ring includes a first channel configured to allow fluid communication between the second end surface and the outer surface.

A variable configuration modular fluid filter assembly includes one or more discrete filter housing assemblies that each include a mount body constructed to support a cap and a filter sleeve. A plurality of bosses are formed on radially outward facing sides of the mount body and are each discretely selectable to fluidly connect the discrete mount body to one another to provide a desired flow characteristic of the discrete filter assembly arrangement. Preferably, each discrete filter assembly includes a seal arrangement disposed between the cap and the mount body and which orients the sealing interface therebetween at an acute angle relative to an axis of rotation of the cap relative to the mount body when the cap and mount body are engaged with one another.

A filter cartridge includes a threaded sleeve having a seal holder recess and seal member. The filter cartridge is for removably threading onto a filter head that includes threads for connection to the filter cartridge by way of the threaded sleeve. The filter head includes a ramp that engages the seal member to form a seal. The force needed to make the seal is a torque of less than 10 N-m.

An oil filter assembly is disclosed for a machine, such as an internal combustion engine, that has an oil output port and an oil input port. A mounting plate is fixed with an outer enclosure. The mounting plate is further adapted to conduct oil from the machine into a peripheral portion of the outer enclosure, and then returning oil from a central portion of the outer enclosure back to the machine. Oil may pass from the peripheral portion to the central portion through a primary filter having a first porosity. A pressure-actuated valve is fixed fluidly between the portions of the outer enclosure.

A method of assembling a canister filter system includes inserting a first filter component into a second filter component, and continuing the insertion until a first tab of either the first filter component or the second filter component contacts the other of the first filter component and the second filter component.

A solids interceptor and methods of using the same. The solids interceptor includes a tank including an open end, a wastewater inlet, and one or more wastewater outlets. A basket assembly is removably attachable to the tank via the open end between an operable position and a removed position. The basket assembly may seal the open end when in the operable position and expose the open end of the tank to a surrounding environment when in the removed position. A first and second outlet may extend away from an interior of the tank in a first and direction, respectively, with the second direction being oriented at an angle with respect to the first direction. The basket assembly may include a seal that is compressed about a circumferentially extending corner provided on the tank to thereby seal the open end of the tank and the plumbing system.
