Abstract

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.
