ABSTRACT:
A fluid filter housing for receipt of a fluid filter element and for threaded attachment to a mounting base includes a unitary, molded plastic shell, an annular, threaded nutplate, and a plastic weld ring. The plastic shell defines a hollow interior for receipt of the fluid filter element. The plastic shell also defines one side of an O-ring groove. The threaded nutplate includes a groove-side surface that defines a second side of the O-ring groove. The weld ring is securely joined to the threaded nutplate by co-molding and is securely joined to the shell by a spin weld process. The weld ring provides a third surface for the O-ring groove. As such, three separate components are used to create an inwardly opening three-sided annular groove for receipt of an annular seal for sealing an interface between the fluid filter housing and the mounting base.
