Cutting Ring Tube Couplings and fitting components comply with the standards, DIN2353/DIN EN ISO 8434-1, with regard to design and dimensions.

During assembly of the coupling, the two cutting edges of the cutting ring penetrate into the tube creating a safe connection. At the same time, the cone of the nut deforms the cutting ring shoudler so that the tube is tightly clampled and able to absorb bending stresses. And radial and axial sealing is assumed by the ring's being wedged between tube and coupling body.
