A pressing tool for pressing fittings to produce pipe connections, with two opposing pressing jaws, each having a pressing section and a lever section, and having a retaining element for swivel connecting the pressing jaws, wherein the pressing sections form a receiving section and wherein pressing the lever sections apart causes the receiving section to close. An actuator spindle, a spindle nut and at least two actuator levers are provided, and each actuator lever is swivel connected at one end to the lever section of a pressing jaw and each actuator lever is swivel connected at another end to the spindle nut. A method for pressing fittings for the production of pipe connections is also disclosed.

Pressing tool for pressing fittings for producing pipe connections and method for pressing fittings

The invention relates to a fitting to be connected to at least one pipe, in particular a plastic pipe or plastic-metal composite pipe, having a main body, having at least one supporting body connected to the main body for insertion into a pipe end and having at least one pressing sleeve connected to the main body for receiving the pipe end, the pressing sleeve having a cylindrical pressing section. The technical problem of improving the fitting for pressing, in particular with small motor-driven or manually driven pressing tools, is solved by the fact that the pressing sleeve is made of a metal with a microhardness of less than 65 HV 1, in particular less than 50 HV 1, preferably in the range from 40 to 50 HV 1 measured according to Vickers, and that the ratio of wall thickness of the pressing section to the outer diameter of the pressing section is less than 0.06, preferably in the range from 0.03 to 0.06. The invention also relates to a method for establishing a connection.
