摘要

High pressure seal comprises a flat seal fitting (9) arranged axially in front of or behind threads (2, 3) radially between a section (6) of a housing (1) of a threaded insert on one side and a wall section of a hole (4) on the other side. The diameter of the housing of the threaded insert and the diameter of the hole is less in the region of the flat seal fitting in the screwing direction so that the seal fitting simultaneously acts as a stop. Preferred Features: A groove (7) for receiving a round cord ring (8) is provided in the region of the seal fitting of the threaded insert. The diameter reduction of the housing in the region of the seal fitting is step-like and forms a stop step.
