A firestop device (10) and firestop assembly for use in a plumbing system (100) installed in a structure to prevent the transmission of smoke and fire through the plumbing system. The firestop device includes a housing (12) with a connector (14) and intumescent material (16) mounted in the inner passageway (12C) of the housing. The firestop device is intended to be mounted over the hub portion (50B) of a plumbing fitting (50). When the housing is heated, the heat is transferred to the intumescent material which expands. As the intumescent material expands, the material crushes the conduit (102) extending through the firestop device and completely blocks the inner passageway (10C) of the firestop device which prevents smoke and fire from moving through the firestop device.
