Abstract

An improved O-ring retainer arrangement for retaining an O-ring on a fuel tube of a fuel injector. An overmolded hard plastic ring is disposed on the cylindrical outer surface of the fuel tube. The end of the fuel tube is radially flared to retain the ring on the tube, the radial extent of the flare being less than or equal to the radial thickness of the ring such that the flare cannot come into contact with the bore of a fuel rail socket. The ring is formed such that axial compressive forces exerted on the ring are outside the fuel tube body and preferably are directly opposed, thus exerting no toroidal torque on the ring. The ring is free to move axially on the fuel tube surface. In one aspect of the invention, the ring can move freely along only a limited region on the fuel tube.
