摘要： The connection piece (1) made of metal for producing a press fit, comprises a first cylindrical section, a second cylindrical section, and a ring bulge (2) adjacent to the first cylindrical section and having an annular groove (3) formed in it for receiving a ring seal. A cross-section of the first cylindrical section is enlarged at its outer side in a first area spaced from the ring bulge, and is reduced at its outer side in a second area (11.1) adjacent to the ring bulge. The second cylindrical section adjoins to the ring bulge at a side opposite to the first cylindrical section. The connection piece (1) made of metal for producing a press fit, comprises a first cylindrical section, a second cylindrical section, and a ring bulge (2) adjacent to the first cylindrical section and having an annular groove (3) formed in it for receiving a ring seal. A cross-section of the first cylindrical section is enlarged at its outer side in a first area spaced from the ring bulge, and is reduced at its outer side in a second area (11.1) adjacent to the ring bulge. The second cylindrical section adjoins to the ring bulge at a side opposite to the first cylindrical section, where a cross-section of the second cylindrical section is enlarged at its outer side in a third area spaced from the ring bulge and is reduced at its outer side in a fourth area (11.2) adjacent to the ring bulge. The second area directly connects to the ring bulge, and is circulatingly formed in a trough-like manner. A maximum depth of the second area has 15-25% of thickness of the cylindrical section. A ratio of the internal diameter of the cylindrical section to an axial distance between first area and the ring bulge is 2.5-6. The connection piece is made of copper alloy with silicon, zinc and copper (80 wt.%), where the copper alloy contains alloy composition. The first area is formed as circulating elevation with trapezoidal cross-section. A maximum height of the first area is 20-35% of the thickness of the cylindrical section. An axial extension of the first area is 2.0-4.0 mm.
