An annular brush seal 502 is disclosed comprising first and second annular clamp plates 504, 506, each clamp plate comprising an opposed annular clamping surface 512, 514, and a pack of radially extending bristles 508 clamped between the clamping surfaces 512, 514 of the clamp plates 504, 506. The clamping surface 512 of at least one of the clamp plates 504 is profiled, such that a separation between the clamping surfaces 512, 514 increases with decreasing radius. A brush seal 102 is also disclosed comprising first and second clamp plates 104, 106, each clamp plate comprising an opposed clamping surface 112, 114, and a bristle pack 108 clamped between the clamping surfaces 112, 114 of the clamp plates 104, 106, wherein the clamping surface 112 of at least one of the clamp plates 104 comprises a linear surface feature 118, 116, 324 extending across the clamping surface 112 and causing a step change in the profile of the clamping surface 112. |
