The cutting rings are divided into 3 series: If the tube is exactly perpendicular cut and deburred, three distinctive points can be sealed in the fully assembled fitting. With dynamic load this fit provides additional support. On the other side, the cutting ring is wedged by the pressure of the nut onto the tube. The tube is pushed into the nozzle base, where it can exert a sealing function with appropriate clean preparation. The cone directs the cutting edge for increased tightening of the nut into the surface of the pipe. When tightening the nut the cutting ring is guided into the connector plug. Furthermore, a cold welding of stainless steel material is prevented in the thread. Through the use of surface-coated coupling nuts, the tightening torque reduces up to 35%. The cutting ring seals the fully assembled screw in three prominent places. In most cases, the specially designed and tested by Germanischer Lloyd Two edge cutting rings are used, which have shown themselves to be very precise and highly reliable a million times. The heart of a cutting ring fitting according to EN ISO 8434-1 (DIN 2353) is the cutting ring.
