The Quick Coupler Socket, which comes in a package of 2, has 1/2" female NPT threads and features internal Viton seals and internal brass-plated construction to withstand use with lawn spraying chemicals.
The Quick Coupler Sockets are intended for chemical and water spray guns and hoses. They are best used with Rittenhouse-made equipment, such as the WideJet, Lawnjet, and Pestjet Spray Guns, and the 8' Overhead Watering Wand.
You will need at least one male plug (available with socket, sold separately) in order to complete the quick coupler set. The male plug can attach to the spray gun and to the quick coupler socket, while the socket will connect to a hose barb, which permits a spray hose connection.
You will not find the quick coupler sockets in local hardware stores.
