An assembly to be mounted in an axle spindle for communicating pressurized air to a rotary union in a tire inflation system. The assembly includes an arbor having an air flow channel extending therethrough, a flange intermediary of the arbor ends and an axially inclined portion proximate the flange. A sealing member is carried by the flange for forming a seal with the axle spindle. A split ring locking assembly is disposed about the inclined portion of the arbor that is comprised of a plurality of segments held by an expansible retention spring. The segments move radially outwardly upon the locking assembly being moved along the inclined arbor portion and engage the axle spindle, securing the plug assembly within the spindle. A fastening member threadably engages the arbor for urging the locking assembly along the inclined arbor portion to effect securement of the plug assembly within the axle spindle.
