An orifice filter suitable for placement in, among other environments, a motor vehicle transmission assemblage, includes a plastic body member with an orifice and filtration material overlying both orifice outlets, all received within a metal housing. A plastic overmold is provided outboard of the filtration material. The filter allows for bidirectional flow of fluid through the assembly, provides for a means of bleeding pressure between fluid volumes in an assemblage, and maintains the secure positioning of the orifice in the assemblage over a range of ambient and operating temperatures. Further, a method of forming a filter assembly, including coining the metal housing of the filter assembly, allows for providing proper dimensional tolerances of the housing axial length and/or housing flange.
