摘要：A spin-on filter cartridge includes a housing, a filter element operably orientedin the housing, a baffle plate, and a seal arrangement. The baffle plate is operablyoriented over the housing open end. The baffle plate defines a central flow aperture. Thebaffle plate defines a continuous groove immediately adjacent to and circumscribing thecentral flow aperture. The seal arrangement is secured to the baffle plate spaced fromand circumscribing the continuous groove. In another aspect, a filter assembly includes aspin-on filter cartridge as characterized above and a filter head. The spin-on filtercartridge is removably mountable on the filter head. The filter head includes a centralspud defining outer threads. An O-ring seal member or a gasket seal member is operablyoriented around the central spud. When the spin-on filter cartridge is operably orientedon the filter head, the seal member is received within the continuous groove and the sealarrangement forms a seal between and against the baffle plate and the filter head. Theseal can be radial or axial or have both axial and radial components. In another aspect, amethod of assembling a filter assembly includes spinning a filter cartridge as

characterized above onto a filter head to form a primary seal between the baffle plate

on the filter cartridge and the filter head, and until a seal member fixed to the filter headis received within the continuous groove. In another aspect, a filter head is provided. Thefilter head includes a block defining fluid flow channels; a central spud having a threadedouter wall; and a seal member secured to and circumscribing the central spud.
