Maximum precision
The VossRing pre-assembly stud consists of high-performance
steel, which does not wear like conventional standard tools; in
addition, its tool service life is 20 times longer. These properties
make wear inspections totally superfluous. Although normal
pre-assembly studs have to be inspected regularly for proper
functioning owing to flaring of the cone contour, this negative
property is absent from the Voss tool. Upon reaching the
application limit, the stud breaks, effectively preventing
assembly errors due to tool wear.
Corrosion protection: Voss coat-Black
The 100 per cent effective design of the new cutting ring
system regarding safety, load bearing capacity and durability
can also be seen in the unique surface quality of the cutting
ring. “The zinc and nickel based coating Voss coat-Black
combats even aggressive media and therefore guarantees
the high corrosion resistance expected by the customer,”
explained Mr Berghaus. As a result, this surface not only attains
corrosion resistance class K5 according to VDMA standard
sheet 24576, but also exceeds the required resistance values
against white and red rust both under laboratory conditions
and in more demanding practical tests.
The new cutting ring system allows even inexperienced fitters to
perform precision work

Conclusion
The new cutting ring system ensures leak-free and process-
reliable tube connection with maximum pressure resistance
and load bearing capacity. Assembly errors are reliably
prevented by the patented limit stop concept. The shorter
final assembly route reduces the required force and makes
the fitter’s work easier, even in constricted installation spaces.
That makes the system reliable and user-friendly.
