    Abstract: A threaded connection and a method for producing such a connection. The threaded connection includes a first and a second tubular component. The first component includes a male end provided on its outer peripheral surface with, in succession, a threaded zone, a sealing surface, and a terminal surface finishing in an abutment surface orientated radially with respect to the axis of revolution of the connection. The second component includes a female end provided on its inner peripheral surface with, in succession, a threaded zone, a sealing surface, and a recess finishing in an abutment surface orientated radially with respect to the axis of revolution of the connection. The threaded zone of the male end is made up into the threaded zone of the female end such that the sealing surfaces are in interfering contact, as are the abutment surfaces, the space between the terminal surface and the recess defining a volume at least partially filled with a filling material.
