ABSTRACT:
A brush seal assembly includes a tab extending outward and engageable with a brush seal retainer. Various construction details are disclosed that provide a tab that prevents rotation of the brush seal during use and also prevents reverse installation of the brush seal assembly. In a particular embodiment, a brush seal assembly for installation within a carrier includes a tab that fits radially within a cut-out in a retaining means. Engagement with the cut-out prevents rotation. The tab extends outward from the low pressured side of the brush seal assembly. If installed in a reverse orientation, the tab engages the carrier to block installation of the retaining means.
