An expansion joint and flexible seal for refractory lined flues includes a flexible insulating body having a pair of end faces, a pair of lateral faces and a longitudinal dimension. The flexible seal further includes a filter element positioned adjacent to one of the end faces and extending in the longitudinal dimension. The filter element is attached to the insulating body and the assembly may be placed with other seal assemblies in endwise fashion around the periphery of a pair of opposing flue members.
