    Abstract: A rotary seal arrangement for use with a central tire inflation system is provided. The rotary seal arrangement comprises a stationary portion, a rotating portion, a first sealing ring, a second sealing ring, and a first bushing portion. The stationary portion defines a first air passage therethrough and the rotating portion defines a second air passage therethrough. The first sealing ring and the second sealing ring are each disposed on one of the rotating portion and the stationary portion. The first bushing is disposed on one of the rotating portion and the stationary portion. The first bushing is in dynamic sealing engagement with the first sealing ring. The stationary portion, the rotating portion, the first sealing ring, and the second sealing ring form a sealed cavity that facilitates fluid communication between the first air passage and the second air passage.
