ABSTRACT:
The connecting piece includes a hollow many-sided head and a hollow screw which forms one piece with the many-sided head. The screw is provided with an external thread so that it can be screwed into the internal thread of a part of a line or an apparatus. A chamber-like circular recess is worked from below into the many-sided head in the proximity of the end of the thread of the screw. The circular recess is worked into the many-sided head in one operation. The cutting tool is first guided into a gate at the end of the thread of the screw perpendicularly to the longitudinal axis of the connecting piece. Thereafter the cutting tool is guided into the bottom surface of the many-sided head in parallel with the longitudinal axis of the connecting piece. In this way a guide surface at the end of the thread of the screw is formed which is free of obstacles. The insertion of the sealing ring into the circular recess is simplified because the sealing ring is guided along the guide surface into the recess without a great effort and without being injured. By tightening the connecting piece the deformation of the sealing ring is limited in an optimal way because the metal of the many-sided head lies on the metal of the part to be connected.
