Abstract
The invention relates to a pipe connector for a pressure-resistant, positive-fit, high pressure screwed joint. The connection includes a formed tube; a screw body or connector branch with a cone, which connects to a parallel axis drilling, with a radial end surface; a union nut; a sealing ring; and a retaining ring. The formed tube has a parallel axis end-piece with the same tube diameter and which corresponds to the depth of the tube seat base. The formed tube has a pronounced head which forms a mating face, with a cone surface of the union nut, and which leads to an abutment face at a front face of the retaining ring, essentially aligned with the tube axis. The retaining ring has a radial ring surface, which, in the assembled state, contacts with the front face of the cone of the connector branch or screw body, and thus permits a block assembly.
