Abstract
Abstract A pipe joint specifically adapted for an oil pump inlet screen, and a method of assembly therefor, comprising a metal pipe adapted at one end to be connected to an oil pump housing and a filter screen including a molded plastic screen housing having an aperture adapted to receive the other pipe end. A metal eyelet is molded into the plastic housing and extends therefrom to embrace a circumferential rib formed on the outside surface of the pipe. An annular resilient sealing ring surrounds the pipe and is captured by the eyelet in sealing compression between the circumferential rib and the housing.
