Abstract

L'invention concerne un corps douille hermétique (1) pour relier de manière étanche deux composants de transmission de fluide, comprenant une paroi interne (2) et une paroi externe (3) qui entoure ladite paroi interne et dont la surface latérale externe (4) est conçue, au moins par sections, pour venir s'appliquer de manière étanche sur l'un des deux composants de transmission de fluide. Une paroi intermédiaire (7) qui est située entre la paroi externe (3) et la paroi interne (2) et dont la surface latérale interne (8) est formée au moins par sections pour venir s'appliquer de manière étanche sur l'autre composant de transmission de fluide. La paroi douille intermédiaire (7) et la paroi douille externe (3) sont reliées de manière flexible. La paroi douille intermédiaire (7) et la paroi douille interne (2) sont reliées. On obtient ainsi un corps douille hermétique offrant une probabilité réduite de défaut d'étanchéité.
