Abstract

Ce manchon 2 d'accouplement en matière plastique pour tuyaux est destiné à être monté sur une extrémité de tuyau 1. Il comporte à son extrémité une nervure interne qui en fait partie intégrante et qui est destinée à porter contre une bague extérieure d'étanchéité d'un tuyau, et à l'autre extrémité un anneau interne élastique d'étanchéité pour porter contre un second tuyau. L'accouplement est réalisé par moulage par injection la bague d étanchéité, puis par moulage par injection du manchon en matière plastique en contact avec la bague d'étanchéité. Ce dispositif s'applique à des tuyaux en matière plastique, en grès, en fibres, fibrociment, béton pour égouts, conduites pour câbles et similaires.
