More Information
Summary:A pipe sealing gasket is shown which is designed to be received within a raceway provided within the female, belled end of a section of plastic pipe which is assembled with a mating male pipe end to form a plastic pipe joint. The gasket is a two-component gasket having a softer, elastomeric portion and a harder, plastic ring portion. A splicing technique is used to form the softer, elastomeric portion with the harder, plastic portion being injection molded over the previously formed elastomeric portion. L'invention concerne un joint d'étanchéité pour tuyau, conçu pour être reçu dans un chemin de roulement situé dans l'extrémité évasée femelle d'une section de tuyau en plastique qui est assemblée avec une extrémité de tuyau mâle complémentaire pour former un raccord de tuyau en plastique. Le joint d'étanchéité est un joint à deux composants ayant une partie élastomère plus souple et une partie annulaire en plastique plus dure. Une technique d'épissage est utilisée pour former la partie élastomère plus souple, la partie en plastique plus dure étant moulée par injection sur la partie élastomère précédemment formée.
