Connection end-fitting for flexible hose

摘要

Connection end-fitting for a flexible hose, made from a tube section 2 in a single component with a sealing head 3 having: a cylindrical part 4 with an external diameter which is greater than that of the section of tube; a collar part 5 with an even larger diameter; and a sealing cone 6 whose external diameter decreases towards the free end of the head 3. The cylindrical part 4 results from a first flared part 7 whose internal diameter D1 is greater than the normal internal diameter D of the tube section 2. This flared part 7 is followed by an annular fold 8 forming the collar part 5, followed by a second flared part 9 with an internal diameter which decreases towards the free end 6a which forms the sealing cone 6. The maximum internal diameter D2 of the second flared part 9 is greater than the normal internal diameter D of the rest of the tube section.
