A brush seal consisting of a annular backing plate, annular side plate and a bundle of bristles disposed axially sandwiched in between serve to transmit the axial load when assembled and eliminate the necessity of seal retaining mechanism such as split rings or retaining plates. The invention is particularly adapted to seal the interface of the combustor and the stator of the first stage turbine of a gas turbine engine.
