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.

Abstract translation: 用于接收流体过滤元件并用于螺纹连接到安装基座的流体过滤器壳体包括单一的模制塑料外壳，环形螺纹螺母板和塑料焊接环。 塑料外壳限定用于接收流体过滤元件的中空内部。 塑料外壳还限定了O形圈槽的一侧。 螺纹螺母板包括限定O形环槽的第二侧的槽侧表面。 焊接环通过共同模制牢固地连接到螺纹螺母板，并通过旋转焊接工艺牢固地接合到壳体。 焊环为O形环槽提供第三表面。 因此，使用三个单独的部件来产生向内开口的三面环形槽，用于接收用于密封流体过滤器壳体和安装基座之间的界面的环形密封件。
