A water filter cartridge assembly for fluid filtration which may be attached to, and removed from an appliance water filter manifold assembly of an appliance, typically by a push-actuated release. The water filter cartridge assembly has a filter housing, and an ingress port and egress port extending therefrom. Each of the ingress port and the egress port typically comprise a port portion having a varying radial diameter. The water filter cartridge assembly further comprises a connection assembly that is structured to establish an electrical connection between the connection assembly and a controller of the appliance. Both of said ingress and egress port have at least one aperture for the passage of fluid therethrough such that each of the at least one aperture is exposed in a direction facing away from the connection assembly.

A system for cover for fuel filters that includes a flexible cylindrical sheet member is disclosed. The sheet member includes a top wall at a first end and a second end that is open. The cylindrical sheet member snugly receives the fuel filter being protected. The sheet member is made out of thermal insulating material such as neoprene. To further conform the open end to the outer shape of the diesel fuel filter, a strap member with pressure sensitive hook and loop fasteners is used.

A filter cartridge has media construction, a housing, and a first end construction. The first end constructions includes an outer radial wall with circumferentially spaced connecting sections; each connecting section having a plurality of helical profiles extending at a helix angle. The filter cartridge is removably attached to a filter head, which has mating connecting segments. A bowl cartridge assembly is also provided including connecting sections with a plurality of helical profiles.

A filter insert (10) comprising: a body portion (12) and a closed-ended tube (14), an open end of which is sealingly affixed around the periphery of the body portion (12); an inlet aperture (16) and an outlet aperture (18) each aperture communicating via a through hole in the body portion (12) with the interior of the tube (14); a filter medium (20) located within the tube (14) and being sealingly interposed between the inlet aperture (16) and the outlet aperture (18), wherein the tube (14) is at least partially manufactured of a flexible plastics material, and wherein the body portion (12) is relatively rigid.

A fluid treatment device has an exchangeable treatment unit and a connection head. A bayonet-type connection device connects connection head and treatment unit to each other by a plug-in/rotation movement about a connection axis of the treatment device and is provided with a housing connection part and a head connection part that operatively engage each other to form a connection of the bayonet-type connection device. Housing connection part and head connection part each have a mutually complementary functional element extending circumferentially about the connection axis and operatively connectable to each other. One functional element has an assembly ramp passing into a first support region perpendicular to the connection axis. The other functional element has a slide region adjoined by a second support region perpendicular to the connection axis. In connection end position, first and second support regions are positioned on top of each other relative to the connection axis.
