A filter insert, a sample vial incorporating a filter insert, a method of using a sample vial containing a filter insert for chemical analysis, and a sample vial kit including a filter insert. The filter insert includes a cylindrical body having a proximal end, a protrusion extending radially from the proximal end of the cylindrical body and configured to set on the open end of a sample vial, a distal end, a cavity extending longitudinally through the cylindrical body from the proximal end to the distal end, and a filter assembly coupled with the distal end of the cylindrical body.

A method for compensating for a variable distance between two components of an apparatus for providing a fluid filtering device therebetween is provided. The method comprises placing an adjustable filtering device between two components, altering the distance between the two components, and compensating for the change in distance between the two components by varying a dimension of the adjustable filtering device.

A showerhead assembly including a filter cartridge assembly having a replaceable filter cartridge. The showerhead assembly includes a water-directing and filtering assembly having a body portion and a face portion removably affixed to the body portion. The filter cartridge assembly includes a split filter cartridge housing and filter cartridge. A first part of the filter cartridge housing is disposed in the body portion and a second part is disposed in the face portion. The filter cartridge includes a casing and spaced apart first and second end walls, an inlet connector extending axially from the first end wall, and an outlet connector extending axially from the second end wall and being offset from the filter cartridge central axis. The second end wall includes a first recess extending linearly between a peripheral edge of the second end wall and terminating at a termination position substantially aligned with the filter cartridge central axis.

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 filter assembly includes a filter housing having a longitudinal axis, the filter housing divided into a first filter chamber and a second filter chamber, a first element bottom endplate, a second element top endplate, an intermediate endplate positioned along the longitudinal axis between the second element top endplate and the first element bottom endplate, a first filter element housed within the first filter chamber and comprising first filter media positioned between the first element bottom endplate and the intermediate endplate, and a second filter element housed within the second filter chamber and comprising second filter media positioned between the second element top endplate and the intermediate endplate.

A replaceable subsea filter uses a hot-stab style connection. The filter has a flow path located along a central axis. At a distal end of the of the filter, the flow path locates inside a subsea receptable, typically associated with a reservoir or sea chest for a hydraulic actuator. At a proximal end, the flow path opens into an annulus around the stab-connecter, the annulus being separated from the surrounding waters by annular filters.

Filtration head (1) for a filter system, comprising base (2) including filter support (3) for removable filter element (4) and a fluid path from one side of filter element (4) on filter support (3), through filter element (4), and to drainage outlet (5) of base (2), and holder device (6) for removably attaching funnel (7) to base (2) to form a sample fluid reservoir on one side of filter element (4), wherein holder device (6) comprises ring-shaped element (8) configured to extend about bottom peripheral flange (7a) surrounding a lower end of funnel (7) and to selectively apply a biasing force on a radially outward protruding portion (7b) of bottom peripheral flange (7a) of funnel (7) to press funnel (7) against base (2). The filtration head allows the use of cardboard funnels without risk of liquid leakage between the funnel and the base.
