A method for modifying a sealing system of a hydrogen-cooled generator includes coupling to a sealing device of the generator a contacting seal comprising a plurality of non-metallic bristles projecting from an aluminum body with tips of the bristles engaging a rotor of the generator. Another method includes removing a portion of a non-contacting seal, providing a replacement sealing device comprising an aluminum body and a plurality of non-metallic bristles projecting therefrom, and replacing the removed portion of the non-contacting seal by coupling the aluminum body to the non-contacting seal such that tips of the bristles contact the rotor. Another method includes removing an original sealing device, providing a replacement sealing device comprising an aluminum body and a plurality of non-metallic bristles projecting therefrom, and inserting the replacement sealing device into the generator such that tips of the bristles contact a rotor of the generator.
