A fluid conveying hose, especially a refrigerant conveying hose, that exhibits improved resistance to permeation of the refrigerant while still affording desirable flexibility, and a fitting for such hose and methods of making the hose and the union between the hose and fitting. Also provided is a coupling assembly for a hose and a service fitting that is a considerably less expensive alternative to existing assemblies equipped with relatively expensive shut-off valves or quick connect/disconnect couplers.
