Abstract
A crossfire tube for attachment between casing bosses of combustors includes a bellows assembly having a bellows with opposite cylindrical ends welded to annular flanges. The annular flanges include a bolt circle for securing the flanges to the combustor bosses. The flanges bear against a gasket for sealing against inserts welded to the casing bosses for retrofit in the sealing assembly to combustors or to seats where the inserts and bosses are formed integrally during original equipment manufacture. A telescoping cylindrical sleeve surrounds the bellows to protect from falling foreign object damage.
