This Quick Coupler Socket and Male Plug combination is required for certain Rittenhouse-made equipment, such as the WideJet, PestJet, and Lawnjet spray guns, and the 8' Overhead Watering Wand. They are recommended to connect to spray hoses and spray guns for all kinds of professional lawn spraying applications.
The Quick Coupler Socket has internal Viton seals and internal brass-plated construction that will easily withstand lawn spraying chemicals, making it suitable for use with chemical and water spray guns and hoses. The male plug attaches to the spray gun and to the quick coupler socket, while the socket connects to a hose barb, which then allows for a connection to a spray hose.
You will not find these quick coupler sockets and plugs in local hardware stores.
