Abstract

A multi-part filter combination is received in a stepped bore of a fluid-carrying component. A larger-diameter filter part is associated with a larger-diameter bore portion, and a smaller-diameter filter part is associated with a smaller-diameter bore portion. The two filter parts of the filter combination are connected by a connecting part. When the two filter parts are joined in their respective final position in the bore, this connecting part is detachable by means of a die to be introduced into the bore. The filter combination can be used in a valve block serving to receive a magnet valve.
