An apparatus for sealing a rotary tube drum of a furnace to another furnace component. Two concentric resilient metal ring segments are provided on a disk to comprise the sealing elements of the present invention. A plurality of springs arranged as a ring apply pressure to the disk and ring segments to ensure a consistent and self-adjusting seal between the joined components. Links located circumferentially about the disk limit lateral movement, yet allow axial movement, of the seal. It is thereby possible, according to the present invention, to provide a resilient seal between a rotary tube and another component of a furnace that yields a self-adjusting gas-impermeable seal between the mating components.
