ABSTRACT:
A coupling device for installation in a building wall or floor to provide a passthrough opening for pipes, tubing, and the like comprises an axially elongated, plastic tubular housing with a radially extending mounting flange and having open first end and a second end which is closed by a transverse wall. At least one tubular coupling element having an entrance end and an exit end is positioned within the housing to extend axially thereof with the entrance end of the coupling opening to the first end of the housing. Intumescent firestop material surrounds the coupling element and fills the space between the coupling element and the outer housing. A tube member extends from the coupling element to the second end of the housing. After the coupling device is installed, the second end of the housing is cut away at the surface level of the partition to expose the tube member for connection to the associated piping system.
