A tap plate is at an end of the canister having a central threaded opening along the central axis of the canister. The tap plate includes a first outer opening radially spaced between the central opening and a periphery of the tap plate. The disc element is supported for rotation on the tap plate. A first keyed protrusion projects outwardly from the disc element. The keyed protrusion defines a first flow opening. The spinning disc element is rotatable about the central axis. The first outer opening is in fluid communication with the first opening of the first keyed protrusion such that fluid can into or out of the canister. Filter systems including a filter head to which the filter element may be mounted are also provided.

Filter element with keyed spinning thread-on attachment

A filter element includes a ring of filtration media circumscribing a central axis and defining a central cavity. An annular end cap of the filter element is sealingly bonded at an end of the media. The end cap includes a central opening into the central cavity, and a lateral opening spaced laterally outward from the central opening. The central opening includes a threaded connection portion to enable the element to be spun-on to a complimentarily-threaded connection portion of a filter head. The connection portion of the central opening includes at least one axially-extending slot opening radially away from the connection portion.
