| description | The utility model provides an efficient sealing metal pipe joint which comprises a metal main body which is integrally arranged, the metal main body sequentially comprises an inner connecting section, a hard sealing tightening section and an auxiliary section from the inner end to the outer end in the axial direction, and the hard sealing tightening section comprises a hard sealing tightening part with a cylindrical outer wall and a first barb. The first barbs are arranged on the inner wall of the hard sealing tightening section and protrude from the inner wall of the hard sealing tightening section to the radial inner side of the hard sealing tightening section, each barb comprises a first concave circle, a second convex circle and a third concave circle, and an inclined circular truncated cone face is formed between each first concave circle and the corresponding second convex circle. The first concave circle is located at the axial outer end of the metal body and corresponds to the large-diameter end of th |
