When installing stainless steel pipes, pre-assembly must only be carried out in the hardened VOMO. Direct assembly in the stainless steel socket must be avoided! The VOMOS cones are subject to wear and must therefore be checked at regular intervals with a cone gauge to ensure that they are true to gauge. To prevent incorrect assembly from the outset, worn VOMOS must be replaced with new ones.

The laser-engraved test number on the media-bearing parts guarantees traceability to the original material and the assignment of the 3.1 certificate with all mechanical tests, even years later. The sizes from 6 to 42 mm and pressures up to 630 bar ensure a wide range of applications for the fittings. The range is rounded off by a choice of thread types (cylindrical, metric, tapered, NPT). Individual and customer-specific solutions are a matter of course thanks to in-house production, as is professional quality management. All parts are available immediately from stock with a DIN EN 10204 certificate.

Tubes: Seamless, soft annealed precision stainless steel tubes made of material 1.4571 in accordance with DIN EN ISO 1127 tolerance class D4/T3 are recommended; do not use welded tubes: the material structure in the area of the weld seam is altered, which can change the cutting behavior of the cutting ring. For cost reasons, however, thin-walled tubes are often used which cannot withstand the pressure of the cutting ring during assembly. We recommend the use of reinforcing sleeves to ensure that the fitting still functions properly.
