A device for installation in a building wall or floor to provide a passthrough opening for pipes, tubing, and the like includes an axially open first end and a second end closed by a transverse wall. A ring of intumescent material fills the axially open first end of the housing, and in one embodiment, a foam plastic filler material substantially fills the housing between the intumescent ring and the transverse wall. The intumescent ring can be provided with a central opening sized to engage with an interference fit a tube or pipe passing through the device. Alternatively, the ring can support a tube coupling for providing a tubular connection within the device to receive and couple pipes on opposite sides of the building wall or floor in which the device is installed.

Cette invention concerne un dispositif à installer dans un mur ou un plancher de bâtiment pour permettre la traversée de canalisations, de tuyaux et autres équipements assimilés. Ce dispositif présente une première extrémité ouverte et une deuxième extrémité fermée par une paroi transversale. Un anneau en matière intumescente obture la première extrémité ouverte, et dans une variante, une mousse plastique comble l'espace entre l'anneau intumescent et la paroi transversale. Une ouverture de diamètre prévu pour un ajustement serré peut être pratiquée au centre de l'anneau intumescent pour permettre l'insertion de la canalisation ou du tuyau devant traverser le mur ou le plancher. Dans une autre variante, l'anneau intumescent peut être muni d'un raccord permettant de relier dans le dispositif des canalisations ou des tuyaux situés de part et d'autre du mur ou du plancher.
