The high-quality U contour press rings have been specially designed and developed by ROTHENBERGER for pressing applications on plastic piping systems. With this press ring design, users are ideally equipped to press fittings in complex assembly situations in accordance with the system. Thanks to the ROTHENBERGER DURA LAZR TEC® technology - an innovative, partial laser hardening process - precise and reliable pressing is ensured, while at the same time increasing the service life. This also results in minimized wear and a doubling of pressing cycles compared to non-treated pressing tools. Furthermore, long-term corrosion protection supports the resistance of the pressing jaws. Thanks to the use of a heavy-duty special steel, ROTHENBERGER press rings are suitable for all commercially available pressing machines with a constant axial thrust force of 19 kN or 32 kN.
