A brush seal is comprised of arcuate seal segments having ends cut in a radial direction with bristles "canted" at an approximate 45.degree. angle relative to radii of the segments, leaving triangular regions adjacent one end of each segment void of bristles at the junction of the segments. The brush seals are retrofit into conventional labyrinth seals with the backing plate for the bristles comprising a labyrinth tooth profile extending fully 360.degree. about the seal, including those areas where bristles are not present or only in the areas where bristles are not present. A support is provided at the juncture of the segments and to which support proximal ends of additional bristles are secured to project at an approximate 45.degree. angle relative to the segments at their juncture. Those additional bristles fill in the triangular region void of bristles when the support is secured to the end of the segment having the void whereby a full 360.degree. array of sealing bristles are provided.

[ What is claimed is:] [1.] An annular brush seal for disposition between a rotatable component having an axis of rotation and another component about said axis, comprising:a plurality of arcuate brush seal segments for forming an annulus about and lying in a plane normal to said axis and between the components, each said brush seal segment including an arcuate array of discrete, generally linearly extending bristles secured to said segment and extending therefrom at angles offset from radii of said segments;each of said brush seal segments having opposite ends, the bristles adjacent a first end of each segment extending at an acute angle relative to said first end of said segment such that a portion of said segment at said first end thereof is void of bristles;a support between said first end of each segment and an end of an adjacent segment;a plurality of bristles secured to each said support and extending therefrom at angles offset from a radius of said segments at said first end of each said segment, said plurality of bristles extending to the first end portions of said segments to provide bristles in said voids at said first ends thereof;each said support being secured to one of said first end and said adjacent end of said segments.
