A brush seal which comprises a plurality of tightly-packed bristles (3) sandwiched in a space between a pair of axially-spaced annular side-plates (1,2). In order to minimize the gaps between the bristles at the outer radius of the seal the cross-sectional area of the space, and/or the bristles is varied, or alternatively the bristles are formed in an involute shape, and the cross-sectional area of the space is constant at all radii.

A brush seal comprising a plurality of tightly-packed bristles sandwiched in a space between a pair of axially-spaced annular side-plates and having free ends projecting in the plane of the seal from a circumferential edge of the side-plate pair, the bristles and the space between the side-plates being dimensioned in relation to each other so that the cross-sectional area of bristle material at any radius substantially completely fills the cross-sectional area of the space between the side-plates at that radius.
