Title: FITTING FOR CONNECTING TO AT LEAST ONE PIPE AND METHOD FOR PRODUCING A CONNECTION
Abstract:
The invention relates to a fitting for connecting to at least one pipe, in particular a plastic pipe or plastic-metal composite pipe, comprising a main body (4), at least one support body (6) connected to the main body (4) and for introducing into a pipe end, and at least one press sleeve (8) connected to the main body (4) and for receiving the pipe end, wherein the press sleeve (8) has a cylindrical press section (10). The technical problem of improving the fitting for pressing, in particular with small motor-driven or hand-operated pressing tools, is achieved in that the press sleeve (8) is produced from a metal with a microhardness of less than 65HV1, in particular less than 50HV1, preferably in the range between 40 and 50HV1, measured according to Vickers hardness test, and in that the ratio of the wall thickness (s) of the press section (10) to the outer diameter (d) of the press section (10) is less than 0.06, preferably in the range between 0.03 and 0.06. The invention also relates to a method for producing a connection.
