The Rothenberger pressing jaws, made from proven materials and manufacturing quality, are suitable for system-compliant crimping of fittings made from metal or plastic systems. By applying a special hardening process, the Dura Lazr Tec technology, and partial laser hardening, precise and secure crimping is achieved while simultaneously increasing durability. The result is minimized wear and 100% more crimping cycles compared to the previous model. Additionally, long-term corrosion protection supports the longevity of the pressing jaws. With the use of a high-strength special steel, the pressing jaws are compatible with all pressing machines that have an axial thrust force of 32 - 34 kN. The Dura Lazr Tec process—partial laser hardening—allows for the highest hardness at highly stressed points. This leads to minimal wear and high contour fidelity. In combination with the forged, high-strength, and flexible special steel, the new generation of pressing jaws achieves a 100% longer lifespan compared to its predecessor. The 3-bolt synchronous mechanism allows the pressing jaw to be opened with one finger. Precision-crafted contours ensure optimal and secure crimping. The standard pressing jaws are suitable for the Romax 4000, Romax 3000 AC, and Romax AC ECO with a constant axial thrust force of 32 - 34 kN and compatible jaw holder. Intermediate jaw for system-compliant crimping of fittings with crimp rings with a diameter of 42 - 54 mm (metal). Features of the pressing jaw system: Standard pressing jaw.
