Abstract

A brush seal assembly including a bristle strip having a plurality of bristles mounted at an angle to at least one rail, and an annular holder for supporting the bristle strip is provided. In one embodiment, the bristle strip is flexible such that the strip can be readily bent by hand and the annular holder is preferably U-shaped. The brush seal assembly may be utilized with conventional mounting techniques, and may be mounted within a unitary or segmented holder. Once installed, the brush seal assembly acts as a static and dynamic seal in order to seal gap between a high pressure source and a low pressure source.
