摘要 |
The invention relates to a pipe joint for joining a tubular component (1) to a receiving piece (2), the pipe joint comprising a fitting body (3) having a recess (8), a tightening nut (6a) having a first thread (7a), the fitting body having a corresponding thread (4), and a cutting ring (9) being arranged to be pressed between a wedge-like wall portion (10) of the recess, and the tubular component when the tightening nut is tightened. In order that the pipe joint could be tightened to form a leak-proof and strong joint using low torque, which enables the use of small tools applicable in confined spaces, the pipe joint comprises a supplementary nut (6b) having a thread (7c) whose handedness corresponds to that of the first thread (7a) but is smaller, the tightening nut comprising a second thread (7b) corresponding to that of the supplementary nut.
