A filter assembly includes a manifold having a male inlet port and the male outlet port and a filter cartridge having a female inlet port and a female outlet port. The male inlet port and the male outlet port are mounted to a spool body such that the male inlet port and the male outlet port extend away from the spool body. The female inlet port and the female outlet port are mounted to a casing at an end portion of the casing. A related refrigerator appliance is also provided.

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.

A filter assembly, a ventilation assembly and an air-conditioning apparatus are provided. The filter assembly includes: a filter screen configured to filter air; a supporting portion configured to support the filter screen arranged to the supporting portion; and a mounting portion configured to mount the filter assembly to or adjacent to a mounting port of an apparatus to be provided with the filter assembly, and a shape and a size of the mounting portion matching with those of the mounting port to cover the mounting port. The mounting portion includes a sealing part having a shape approximately the same with a shape of a gap between the mounting portion and the mounting port and has an interference fit with the gap, to seal the gap between the mounting portion and the mounting port.

A system is provided for removing oil from an oil filter of a motor vehicle. The system includes a housing with a top rim, an upper portion, a lower portion, and a bottom rim. The top rim of the housing includes a first diameter. The housing includes the bottom rim with a second diameter that is less than the first diameter. The system also includes an upper cap with a flange including a first side and an opposing second side. The flange is disposed at a top portion of the upper cap. The first side of the flange is coupled to the top rim of the housing. A bottom portion of the upper cap extends into the housing. The upper cap includes a central aperture for draining the oil from the oil filter into the housing.

A fuel filter device for operation in a position under non-extreme conditions, when there is enough time for replacement of the clogged filter element, or in a reverse position in a fuel bypassing state for non-stop operation under extreme conditions, when there is no time for replacement of the clogged filter element. The device consists of cup-shaped members, which are interconnected through a threaded connection and form a cavity that contains a spring compressed between the bottom of an opening of one of the cup-shaped members and an abutment formed between two openings of another cup-shaped member. The compression force of the spring is applied to a seal ring placed into an annular groove formed in the abutment surface through a flange of the filter element. Another improved sealing feature is provided by a second seal ring, which seals the threaded connection, when the connection is tightened.

A sealing element (5) for a filter element (2) in a housing body (1) of a filtration system, preferably in a cross-flow filtration system. The sealing element (5) is one piece and is annular in shape and comprises one section for sealingly arranging the filter element (2) in the housing body (1) and one section for impact damping for the filter element (2)

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.

A filter assembly for an engine, has: a housing having a longitudinal axis and defining an internal volume, the housing having an open end; and a cartridge assembly receivable within the internal volume via the open end of the housing and securable to the housing, the cartridge assembly including a filter cartridge, a cover removably secured to the filter cartridge, and a sealing member between the cover and the filter cartridge, a locking engagement between the cover and the filter cartridge to limit an axial movement of the cover relative to the filter cartridge upon removal of the cartridge assembly from the housing.

A filter cartridge includes an open-ended housing and filter element supported in the housing and defining an annular region between a periphery of the filter element and a side housing wall. A water collection region is between an end of the filter element and a lower-housing wall. The filter element includes pleated media surrounding an axially-extending central area, and pleats of different heights round the central area. An end plate is bonded to the filter element to prevent fluid flow through the pleats' upper ends. One passage is through a plate opening into the central area. Another passage is between the end plate and peripheral region. The filter element has freely-supported lower ends. A seal between the lower periphery of the filter element and the housing prevents fluid bypass of the filter element. Fluid passes through the pleats, and water coalesces on the media and drains into the collection region.

In some examples, a filter assembly may include a filter including a first gasket having a first channel adjacent to a first side of the filter and a second gasket having a second channel adjacent to a second side of the filter. The first gasket and the second gasket may include a beveled surface adjacent to the filter. The first channel and the second channel may include a diameter of from about 0.01 mm to about 0.5 mm. A finger tightening system may securely hold the filter without any leaks.
