ROTARY UNION

This is a rotary union retrofit kit for the Hendrickson TIREMAAX automatic tire inflation system on trailers. It allows compressed air to travel from the stationary axle to the rotating wheel end, so tire pressure stays at the set level while the vehicle moves. The kit is used when the original rotary union leaks or fails, causing constant air loss and low tire pressure, or when upgrading early TIREMAAX CP or EC systems to the latest sealing design.
