A combination gladhand and dirt protection plug for use in gladhand coupling applications, for example with a tractor and/or trailer. There is a gladhand body with an air inlet and an air outlet. A seal member is positioned at the air outlet and there is a chamber in the body connecting the inlet and the outlet. A dirt protection plug is positioned within the chamber and there is a handle for moving it reciprocally or coaxially in the chamber between positions opening and closing communication between said inlet and outlet. The dirt protection plug carries a nose portion which penetrates the outlet seal in the closed position of the gladhand to prevent dirt and other foreign matter from entering the gladhand body chamber. The dirt protection plug carries a closing seal which is in sealing engagement with the chamber walls to close communication between the inlet and outlet in the closed position of the plug.
