Abstract
A brush seal assembly is disclosed that includes bristles arranged circumferentially about an axis to provide a bristle assembly. First and second plates are secured about the bristle assembly to provide a subassembly. A circumference of the subassembly is pressed into a retaining ring to provide the brush seal assembly. The circumference need not be machined. A perimeter weld is no longer needed to secure the first and second plates and bristle assembly to one another to provide the brush seal assembly.
