<p>The invention firstly relates to a method for the pressing of a press fit ting (3), with a tube (2) inserted into the press fitting (3), by means of a pressing tool (1), wherein the press fitting (3) has an encircling bead (31 ) in which an O-sealing ring (32) is placed, wherein the tube (2) ends withi n the press fitting (3) and a first pressing is carried out within the bead (31), wherein, furthermore, a further pressing is carried out on the tube-in sert side of the press fitting (3) at a distance from the bead, the further pressing leading to press fitting (3) and tube (2) obtaining a conicity whic h prevents them being pulled off and runs in the same direction. Furthermore , the invention relates to a pressing tool (1) suitable for carrying out the method. In order to further improve a method of the type under discussion, in particular for simplifying the handling over the course of the pressing o peration, and in order to improve a pressing tool of the type under discussi on, in particular in terms of handling while maintaining the functional reli ability of the press connection which is to be produced, it is proposed, in terms of the method, that the bead (31) is widened axially over the course o f the pressing operation by being acted upon radially from the outside. In t erms of the object, it is provided that the first pressing geometry (21), wh ich is assigned to the bead (31), leaves the bead (31) space at least in one direction for the axial widening of the bead (31).</p> |
