A filter part for fluid lines, preferably high-pressure lines with pressures in the range of 150 to 900 bar, preferably in the range of 200 to 350 bar, more preferably in the range of 700 to 875 bar, for use especially in filling nipples, non-return valves, pressure regulators, cylinder valves, filling couplings, switching valves, break-off safety devices, quick couplings and also as a separate filter part. The filter part comprises a base body and at least one fluid passage opening, wherein the base body and the fluid passage opening are covered by at least one filter element. The invention further relates to a method for producing a filter part with a base body and a filter element, especially in form of a screen filter which is also known as a filter mesh.
