摘要：The invention relates to a cutting ring fitting, comprising a coupling nut and atleast one cutting ring for the production of pipe threads. A conical or cylindrical externalring surface (8, 9) of the cutting ring (2), or a corresponding conical or cylindrical internalsurface (5, 3) of the coupling nut (1), comprises a means for fixing the coupling nut to atleast one cutting ring. Said means for fixing the coupling nut (1) to at least one cuttingring (2) is embodied as a bonding agent, or comprises a plastic or elastomeric ring (11, 13,16, 18), the outer diameter of which matches the root diameter of the correspondinginner surface of the coupling nut (1). The plastic or elastomeric ring (11) is pressed orpushed onto the corresponding external ring surface (9) of the cutting ring (2), or into thecorresponding internal surface (4, 3) of the coupling nut (1) in such a way as to form apress-fit. In a further embodiment the plastic or elastomeric ring (11) is glued to thecorresponding external ring surface (9) of the cutting ring (2) or the correspondinginternal surface (5) of the coupling nut (1). Furthermore plastic or elastomeric rings withfixing elements such as steps, channels or spurs can be used.
