A flexible sealing assembly () for an optical fiber draw furnace () comprising a first plurality of curved ring sections () arranged in a circular arrangement and a plurality of tension loaders () exerting continuous radially inward force on at least one curved ring section. Each curved ring section of the first plurality of curved ring sections () is separated from each other and defined by the same radius of curvature. Further, the first plurality of curved ring sections () is radially movable such that the first plurality of curved ring sections () creates a seal between a glass preform () and a vertical hollow body () in the optical fiber draw furnace (). The diameter of the glass preform () varies.
