Abstract (en)

[origin: WO2016102104A1] A device (1) of a fuel injection system has a fuel-conducting component (2) and a connecting part (3). A metal-to-metal sealing connection arrangement (4) is provided which comprises a first metal connection partner (6) and a second metal connection partner (5). The metal connection partners (5, 6) can be connected to each another with respect to an axis (12), with a conical sealing surface (15) on the first connection partner (6) and a sealing contour (19) matching the conical sealing surface (15) of the first connection partner (6) on the second connection partner (5). The sealing contour (19) of the second connection partner (5) has, in an initial state, a circumferential elevation (18) around the axis (14), said elevation facing the conical sealing surface (15) of the first sealing partner (6), wherein the sealing contour (19) of the second connection partner (5) is configured such that, with the screwing of the first connection partner (6) to the second connection partner (5), the circumferential elevation (18) of the second connection partner (5) is at least partially plastically deformed, in order to form a metal-to-metal seal between the conical sealing surface (15) of the first connection partner (6) and the elevation (18) of the second connection partner (5) that is deformed in the screwed state.
