The Rothenberger pressing loops, made with proven material and manufacturing quality, are suitable for system-compliant pressing of fittings made from metal or plastic systems. The application of a special hardening process, the Dura Lazr Tec technology, along with partial laser hardening, enables precise and secure pressing while simultaneously increasing durability. Additionally, a long-term corrosion protection enhances the longevity of the pressing loops. Utilizing a high-strength special steel, the pressing loops are compatible with all pressing machines that have an axial thrust force of 32 to 34 kN. The Dura Lazr Tec process – partial laser hardening – allows for the highest hardness level at highly stressed points, resulting in minimal wear and high contour fidelity. Combined with the forged, high-strength, and flexible special steel, the new generation of pressing loops achieves 100% longer durability compared to its predecessor. The 3-segment design allows for optimal force distribution around the fitting. Two movable sliding segments ensure optimal material flow at the fitting. Precision-manufactured contours for optimal and secure pressings. The standard pressing loops are suitable for the Romax 4000, Romax 3000 AC, and Romax AC ECO with a constant axial thrust force of 32 to 34 kN and compatible pressing jaw reception. Pressing loops for system-compliant pressing of fittings with a diameter of Ø 42 to 54 mm (metal) and corresponding compatible pressing jaw reception. Features of the pressing jaw system: Standard pressing jaw contour: SV.
