The typical LOKRING union joint consists of two LOKRINGs and one tubular joint for the acceptance of the two tube ends. Thanks to the conical inner contour of the LOKRING and the special outer contour of the joint, the diameter of the connection is reduced during assembly to such an extent that the joint and the tube create a hermetically sealed metal-to-metal connection. The lifetime gas-tightness of the fitted connection is ensured by the state of permanent elastic pre-tension, which is produced by the radial forces of the LOKRINGs acting in the opposite direction to the tube-joint connection.
Our patented hand assembly tools were developed
especially for LOKRING assembly.
You only need one tool, because the assembly jaws can be exchanged quickly and easily. Since the handles are offset on both sides, the HMRK-V is also suitable for flexible use during work in hard-to-reach areas.
- Specially developed for the LOKRING assembly.
- Patented lever mechanism for assembly with minimum effort.
- Assembly jaws are easy to change for different tube diameters.
- Both handles bend for use in hard-to-reach areas.
- Made in Germany!
