Threaded fitting connection as well as fitting and axial sealing for such a threaded fitting connection and use of a threaded fitting connection

摘要

The coupling (108) has an opening provided at one of two fluid guiding components, and a coupling (110) screwed in the opening. A sealing surface (118) arranged at the coupling is designed as a stop adjacent to an external thread of the coupling. An unit is provided in area of inner diameter of a ring-shaped axial sealing (20). The axial sealing is centrically positioned in area of an undercut in an operation condition. The undercut is provided at the thread side. Independent claims are also included for the following: (1) a coupling for a pressure-tight screw coupling (2) a ring-shaped axial sealing for a pressure-tight screw coupling.
