A piston-cylinder unit for a hydraulic system, especially for the actuation of clutches in motor vehicles, comprises a housing with an axially stepped bore hole in which a piston fastened to a tappet is guided so as to be axially displaceable. The piston displaces a fluid in the cylinder of the housing by its front end. The cylinder includes at least one pressure line connector, a connection to a fluid chamber, and at least one cup which is sealingly arranged in the housing relative to the outer surface of the piston. Both the housing and the piston comprise assemblies made of a plurality of parts. The assemblies are constructed by inserting the plurality of parts in order into a larger part and press fitting them in place.
