Press fitting element

A metallic press fitting element for providing a non-detachable, tight joint of pipes, comprising

• a main body defined by a longitudinal axis and having a radially outwardly projecting bead area at an entry side of a pipe to be inserted, a first cylindrical portion extending inwardly, at a distance to the entry side, of the bead area and connected thereto via a slanted transition, a second cylindrical portion extending inwardly of the first cylindrical portion at formation of a stop surface for limiting a movement of the pipe being inserted, said bead area terminating in a straight end portion which extends perpendicular to the longitudinal axis in a radial direction and has a terminal end which bounds a circular opening, said straight end portion having a wall thickness which is equal to a wall thickness of the bead area and of the first cylindrical portion;
• and
• a sealing ring received in the bead area and forming a torus in an non-deformed condition, said sealing ring having an inner diameter which is at least equal to or greater than an inner diameter of the first cylindrical portion, wherein the bead area with contained sealing ring and the first cylindrical portion define a pressing zone which is acted upon by at least two clamping jaws of a pressing tool, when the clamping jaws are closed,
• wherein the circular opening has a diameter which is greater than the inner diameter of the first cylindrical portion by 0.8 mm±0.2 mm.
