Abstract: A seal for a gas turbine engine may include a first cartridge, a second cartridge, and a wave spring. The wave spring may be located between the first cartridge and the second cartridge. The first cartridge may contact a first component to form a seal. The second cartridge may contact a second component to form a seal. The first cartridge may contact the second cartridge to form a seal. The wave spring may force the first cartridge to contact the first component, and the wave spring may force the second cartridge to contact the second component.
