ABSTRACT:
In a fluid system such as irrigation system, fluid conduit attachment is facilitated through the use of a coupling. The coupling may have a body with a first end attached to a component such as an irrigation component, and a second end designed to receive an end of a conduit. The first end may be integrally formed with the component or separately attached thereto. The second end has a bore into which the end of the conduit is inserted. A gripping mechanism is seated in the bore to grip the end of the conduit. A release mechanism slides to release the conduit. The coupling may have a bend and/or branches extending to extra ends. A second coupling may be added to form a rotatable swing joint. An indicator such as a blue color may be used to indicate compatibility of the coupling with the conduit.
