Pipe Crimping Pliers - 40 kN - extendable handles

I bought the device and wanted to use it to press 28mm copper press fittings V-profile, from the brand that gives the pressing contour the V, but the connection was not pressed properly because the press jaws have an unsuitable shape. The edge at the end of the halves is so sharp that a considerable amount of material is sheared off and is placed between the jaws during the pressing process (layer thickness approx. 1mm). This means that proper pressing is no longer possible. The connection is tight, but since it is shaky, this will not last. As a result, I have now bought a professional pressing machine; the edges at the end of the half-shells are bevelled, which means that no material is sheared off. Conclusion: Ideal device if you are looking for an expensive paperweight, I'll count it as a lesson.

The pipe pressing pliers work excellently with 15mm copper pipe; all pressings were tight straight away. However, it can only be used if there is enough space, as the pliers must be completely opened to enclose the fittings.
