Patent ID: 7146839

Claim:
Press tool for pressing a receiving part of a fitting onto a pipe inserted into the fitting, the pressed-on receiving part having a sealing section with an outer shape substantially constantly curved in a circumferential direction and within a predetermined shape tolerance, said press tool comprising: two elastically-deformable press elements, each having: a first end, a pressing region, assigned to the sealing section, having an inner shape that at least partially departs from a constant curvature in a circumferential direction, and a second end having a force input region and a stop surface; and a hinge coupling the press elements together at the first end of each press element, wherein when the press tool is closed, the stop surfaces of the press elements abut one another, and when the press tool is closed and a pressing force is applied to the force input regions of the press elements, the press elements elastically deform such that the inner shape of the pressing regions are substantially constantly curved in the circumferential direction.
