A pressure pipe fitting for feeding high-pressure fuel to, and discharging fuel from, an injector of a common-rail injection system of an internal combustion engine includes at least one inner pipe and an outer pipe coaxially arranged with the inner pipe, with an annular space formed between the outer and inner pipes, and an intermediate piece arranged in the annular space for coaxially positioning the inner pipe and the outer pipe. The inner pipe preferably has conical seat surface on its end face. A threaded connection is provided to position the intermediate piece at a defined axial distance from the seat surface on the inner pipe. The inner pipe comprises a stop acting in the axial direction and cooperating with a counter-stop of the intermediate piece. |
