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.

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.
