ABSTRACT:
A sealing device for assuring a sealed junction between two ducts (3 and 11, 13) for conveying plastic material at a high temperature and under high pressure in a machine for transforming plastic material, includes a first part (2) defining the first duct (3) and a second part (9) defining the second duct (11, 13), the second part being inserted in the first duct. The second part (9) comprises at one end an annular lip (16) protruding from its external cylindrical surface and connected to the one end by a thin annular zone (17). The lip (16) has a cylindrical external surface (18) which abuts the internal surface of the first part (2) under a mechanical bias due to the dimensional tolerances of the external surface (18) of the lip (16) and the internal surface of the first cylindrical part (2).
