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.

A brush seal for discouraging fluid flow through an annular spacing between a stationay carrier and a rotating surface proximate to the carrier, the annular spacing disposed about a longitudinal axis and separating a first cavity and a second cavity, the first cavity having a higher pressure than the second cavity, the carrier including a retaining means being engageable with the brush seal and thereby fixedly retain the brush seal to the carrier with the brush seal in an installed condition, the brush seal including: at least one brush stage, the brush stage including: an array of brushes extending through the spacing; a backing plate adjacent the side of the array of brushes, the backing plate facing the second cavity with the brush seal in the installed condition; and a sideplate adjacent the opposite side of the array of brushes; and a tab disposed in a fixed relationship to the brush stage, the tab engaging the retaining means to block rotation of the brush stage about the longitudinal axis, and the tab extending outward from the brush seal, the tab being located such that if the brush seal is installed with the backing plate between the array of brushes and the first cavity, the tab interfaces with the carrier to thereby prevent fixed retention of the brush seal to the carrier by the retaining means.
