A sealing system may include a bulb seal coupled to a first component and a spring coupled to a second component. The bulb seal may contact the spring to form a seal between the first component and the second component. The bulb seal may be relatively stiff when new and cause the spring to compress. The bulb seal may be relatively flexible as it ages, and the spring may cause the bulb seal to compress. The bulb seal and the spring may maintain a seal throughout the life of the sealing system. The sealing system may maintain a constant separation between the first component and the second component throughout the life of the sealing system.
