Patent ID: 10107399

Abstract:
The invention is a method for manufacturing a sealing joint, comprising coupling a first joint element (14) and a second joint element (20) to each other, and in the course of the coupling applying a first joint element (14) being made of metal and comprising a receiving neck (15) having a receiving aperture (13), and a second joint element (20) having a connecting neck (10) with a shape fitting into the receiving neck (15), being made of plastic comprising at least 90 wt % polymer, and being provided with a protrusion (12) formed around the connecting neck (10) and having a larger periphery than the receiving aperture (13), and manufacturing out of the material of the protrusion (12) in a high-elastic state of the polymer a round-formed sealing collar (28) providing a gas-tight seal between the connecting neck (10) and the receiving neck (15) by pressing the connecting neck (10) into the receiving aperture (13) by means of a force parallel with a longitudinal axis of the receiving neck (15), and by applying the receiving neck (15) for subjecting the protrusion (12) to permanent shear deformation. The invention is furthermore a sealing joint.
