    Abstract: A spin-on filter cartridge includes a housing, a filter element operably oriented in the housing, a baffle plate, and a seal arrangement. The baffle plate is operably oriented over the housing open end. The baffle plate defines a central flow aperture. The baffle plate defines a continuous groove immediately adjacent to and circumscribing the central flow aperture. The seal arrangement is secured to the baffle plate spaced from and circumscribing the continuous groove. In another aspect, a filter assembly includes a spin-on filter cartridge as characterized above and a filter head. The spin-on filter cartridge is removably mountable on the filter head. The filter head includes a central spud defining outer threads. An O-ring seal member or a gasket seal member is operably oriented around the central spud. When the spin-on filter cartridge is operably oriented on the filter head, the seal member is received within the continuous groove and the seal arrangement forms a seal between and against the baffle plate and the filter head. The seal can be radial or axial or have both axial and radial components. In another aspect, a method 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 head is received within the continuous groove. In another aspect, a filter head is provided. The filter head includes a block defining fluid flow channels; a central spud having a threaded outer wall; and a seal member secured to and circumscribing the central spud.
