ABSTRACT:
A misting system including a locking T coupler with an elongated tubular body having a first end defining an axially extending chamber therein with sidewalls that taper radially outwardly from adjacent the first end toward the center of the body. A tubular ferrule is designed to axially nest within the first end of the body with a first end of the ferrule positioned in the chamber for receiving a supply tube coaxially in a second end thereof. The first end of the ferrule further including axially extending fingers with radially outwardly extending portions positioned to engage the tapered sidewalls of the chamber and force the fingers radially inwardly into a tube gripping position as the ferrule is partially withdrawn from the body so as to tightly grip a supply tube positioned therein and prevent the withdrawal of the supply tube from the ferrule. An automatic drain valve is designed to include a check valve and either be engaged in the ferrule or to be threadedly engaged in a nozzle opening of the misting system.
