Type 85

There is a compact device for pre-assembling rings from ZAKO flared flange with an outer tube diameter of 114.3 mm: The VOSS Type 85. The two-part set-up in the assembly cylinder with assembly head and external hydraulic unit make it space-saving and transportable. The VOSS ring is used directly for beading. Since the tool is simultaneously a part of the tube connection, tool wear and over-tightening are essentially excluded. The system is structured in such an attractively simple way that easy pre-assembly with highest precision can be guaranteed.

Suitable for pre-assembly of ZAKO rings.


  • Tool remains in the tube, which means no wear
  • Easy operation
  • The complete assembly process is visible
  • Transportable
  • Suitable for individual or series manufacture
