The air hose to water hose adapter includes a water hose connector having a first cylindrical tube at the front thereof adapted to be rigidly connected to a hose line, and a rear, second larger cylindrical tube, internally threaded, rotatably connected to the first tube. A novel air hose connector is releasably received in the rear portion of the water hose connector and includes an externally threaded generally cylindrical fitting which can abut an internal shelf in the water hose connector and has a central passageway therein, and an elastomeric plug releasably secured in that fitting passageway. The plug has a rounded front end adapted to protrude into the first tube of the water hose connector and plug it tight. The plug front end has a rear flange or shelf which seats firmly in a recessed ring at the front of the air hose fitting, and the plug also has an elongated intermediate portion in the fitting passageway, with external sealing ring engageable with the fitting. The rear end of the plug protrudes through the rear of the fitting and bears an air hose nipple and cap. The nipple communicates with a central air channel running the length of the plug. The rear of the air hose fitting has an integral hex nut which, along with the air hose nipple, is useful for screwing the air hose connector as a unit into and out of the water hose connector.
