Abstract

Devices and methods for manufacturing fittings (2) with different ends (3, 4) are disclosed, such fittings permitting different measures of connection. For example, one fitting (2) is a threaded end connector with its one end (4) being potentially configured as a compression fitting and its other end (3) as a thread-bearing end. An intermediate section (5) having preferably a polygonal cross-section is provided between the two ends (3, 4). Starting with a pipe piece (1), the manufacture takes place in a few process-safe method steps.
