Abstract

A brush seal (10) includes a brush seal body (12) formed of heat-resistant magnetic silicone rubber material in the form of a channel. Bristles (14) are disposed in the channel of the brush seal body at a cant angle and project from the edges of the body terminating in bristle tips (17). The brush seal is formed linearly and, in use, flexed to form an annular seal between adjacent annular sealing components, with the seal carried by one component and the bristle tips engaging the opposite component. The magnetic material of the seal body enables temporary securement of the seal to one of the components, while the seal is adjusted and finally secured in place.
