A double brush seal for sealing the combustor-turbine nozzle interface of a gas turbine engine includes a stationary support member and an intermediate plate attached to the stationary support member. The brush seal also includes a first end plate located upstream of the intermediate plate and attached to the stationary support member, and a second end plate located downstream of the intermediate plate and attached to the stationary support member. A first bristle pack is disposed between the first end plate and the intermediate plate, and a second bristle pack is disposed between the second end plate and the intermediate plate such that the intermediate plate functions as a common back plate for the two stages of the seal.
