Abstract

A method for manufacturing a fitting. The method steps include: providing a pipe section; pressurizing the pipe section; forming a first end of the pipe section to create a press-fit connection having a smooth-walled seat for insertion of at least one of sealing and holding elements; forming a middle section to create a pipe-like polygonal-shaped element and a thickened section adjacent to the polygonal-shaped element; and cutting in a thread on a second end of the pipe section, thereby creating a fitting having a press-fit connection and threaded connection.
