Patent

CA 2534383

A seal for an exhaust duct includes a metal mesh member sandwiched between an outer plate and an inner plate. The seal includes a plurality of flexible members defined by a plurality of slots in both the inner and outer plates. The flexible members provide for expansion and contraction along with creating flexibility in the region of contact between the seal land and the seal. The metal mesh member substantially eliminates gaps and leak paths created through the slots. The metal mesh member is composed of a plurality of interwoven wire strands impregnated with a high temperature elastomeric sealant. The impregnation of high temperature elastomeric sealant over the metal mesh member improves sealing while maintaining the desired flexibility of the seal.
