The seal assembly has a plurality of brush seal elements each of which comprises a generally arcuate carrier and a plurality of bristles projecting therefrom. All of the brush seal elements are supported in the engine housing in a substantially continuous end-to-end manner with the bristles of the seal elements arranged to form a substantially continuous brush seal wiping against the shaft.
