Assembly group for a press fitting, press fitting and assembly method for a press fitting

An assembly method for a press fitting, comprising:

• fastening a stop ring to a first axial end of a pressing sleeve;
• relative tilting of an axis of symmetry of the pressing sleeve with respect to a central axis of a fitting body;
• in the tilted state, applying the pressing sleeve with the stop ring attached thereto to the fitting body with the first axial end first;
• and
• latching the pressing sleeve and/or the stop ring with a groove of the fitting body, wherein the axis of symmetry of the pressing sleeve after latching substantially coincides with the central axis of the fitting body.

An assembly group for a press fitting, comprising:

• a substantially cylindrical pressing sleeve having a pressing area;
• and
• a stop ring fixed to a first axial end of the pressing sleeve and delimiting the pressing area in an axial direction of the pressing sleeve, the stop ring comprising:
• a first inner contour on a side opposite the pressing area for applying the assembly group to a fitting body of the press fitting;
• a first circular segment and a second circular segment adjacent thereto and extending over a smaller portion of the first inner contour than the first circular segment;
• a cross-section which is constant in a region of the first circular segment;
• and
• an element arranged in a region of the second circular segment and projecting inwardly beyond the constant cross-section of the first circular segment so that, when the assembly group is applied to the fitting body, it causes a relative tilting of an axis of symmetry of the pressing sleeve with respect to a central axis of the fitting body,
• wherein the stop ring has, on a side facing the pressing area, a second inner contour with projecting first areas and second areas receding with respect to the first areas for fixing the stop ring to the pressing sleeve.
