Abstract: A connection arrangement for a tire inflation system. The connection arrangement includes a rotary union and a hose assembly. A main body of the hose assembly is insertable into and removeable from a receptacle cavity of the rotary union when in a first rotational position. A locking protrusion of the hose assembly is received in the locking opening of the rotary union to secure the main body to the rotary union when in the second rotational position.

Abstract: An axle assembly having a hose, a spindle plug, a sleeve, and a rotary union adapted to be fluidly connected to a tire. The spindle plug may be disposed in a spindle. The hose may be fluidly connected to the rotary union. The sleeve may encircle the hose and extend from the spindle plug to a stator of the rotary union. The sleeve cooperates with the spindle plug to limit rotation of the stator and the hose.
