AssureFlex® FireSeal Bellows

The AssureFlex FireSeal Bellows is designed to maintain a fire seal around piping that passes through floors, walls, or ceilings while accommodating axial pipe movement caused by thermal expansion and contraction. The flexible metal bellows allows the piping to move without relying on traditional firestop packing that can crack, separate, or drop out as the pipe moves.
