ABSTRACT:
A fire-resistant seal formed of an inner layer (20) of elastomer material that is compressible and flexible, a middle layer (22) of ceramic fiber that is fire resistant, and an outer layer (24) of elastic fabric. In the preferred embodiment, the ceramic fiber middle layer (22) totally encloses the elastomer inner layer (20), and the wear-resistant outer layer (24) totally encloses the middle layer (22) and the inner layer (20). In this particular application, the fire-resistant seal (10) has a toroidal-shaped compressible portion (12) and an integrally formed flange portion (14).
