ABSTRACT:
Penetrations or passageways through fire rated or fire resistant walls, floors, partitions, and ceilings are frequently necessary to provide for present or future pipes, cables or conduits. A fitting placed in the penetration provides a seal to prevent the passing of fire, products of combustion, gas vapor or liquid through the penetration under normal conditions and under adverse conditions of fire or elevated temperatures. The fitting includes an elastomeric-like material, under pressure, which provides the initial barrier. An intumescent material, which responds to heat is provided to expand and fill any void created by the degeneration of the elastomeric material in response to the heat or fire. The fitting may include an outer exposed layer of intumescent material to serve as an insulator.
