Abstract

L'invention concerne un dispositif de raccordement (10, 110) pour fluide avec un site de raccordement (11, 111) étanche comprenant une première portion à diamètre plus élevé (15, 122), une seconde portion à diamètre plus petit (16, 123) et une région de déformation arrondie (19, 124) qui fait partie de la première portion à diamètre plus élevé (15, 122) et de la seconde portion à diamètre plus petit (16, 123) à l'endroit où ces deux portions se rejoignent. La première portion à diamètre plus élevé (15, 122) a une surface interne séparée pour recevoir un bouchon (116) permettant de fermer d'une manière étanche aux fluides, le site de raccordement, alors que la seconde portion à diamètre plus petit (16, 123) est prévue pour recevoir et immobiliser, d'une manière sûre, des adaptateurs mâles de différentes tailles utilisés pour la fixation aux parois d'un passage. Egalement, la région arrondie déformable (19, 124) forme une structure tampon entre la première portion à diamètre plus élevé (15, 122) et la seconde portion à diamètre plus petit (16, 123) pour conserver le diamètre de la première portion à diamètre plus élevé (15, 122) quand la seconde portion à diamètre plus petit (16, 123) est étirée par l'insertion prolongée d'un adaptateur mâle non conformable. En plus, un adaptateur (132) est prévu pour assurer une certaine flexibilité d'utilisation et pour constituer un joint d'étanchéité additionnel, qui ne présente pas de fluage.
