Abstract: A filter element includes in an end cap assembly an internal bypass valve such that the bypass valve can be replaced along with the filter element. Additionally or alternatively, the filter element end cap assembly has a reverse flow valve for enabling reverse flow across the filter element without passage through filter element.

Abstract: A filter assembly includes a filter housing configured as a singular unitary component defining a fluid flow passage through the filter assembly. A filter element is fixed within the housing and spaced apart from both ends of the filter housing to filter a fluid as the fluid flows through the filter housing. A method of insert molding a filter assembly includes providing a mold shaped to form the filter housing as a singular unitary component, locating a filter element in the mold at a location corresponding to where the filter element is to be fixed within the filter housing, and injection molding a molten plastic filter housing material around the filter element such that a portion of the filter element is encapsulated by the molten plastic filter housing material to form the filter housing in a manner that bonds the filter element in place within the filter housing. The filter assembly alternatively may be made by 3D printing the filter housing around the filter element.
