An apparatus and method for preventing the occurrence of free fluid in a fluid delivery system consists of a valve having a sealing element and elongate body disposed within the lumen of a flexible tube. The elongate body of the valve if further disposed within the inlet port of a connector. The perimeter of the sealing element and lumen of the flexible tube provide a tight seal preventing fluid flow when the flexible tube is in a relaxed state or when the longitudinal axis of the flexible tube is in alignment with the axis of the inlet port. The medical fluid is allowed to flow when the longitudinal axis of the flexible tube is not in alignment, e.g., when angularly stretched, with the axis of the inlet port.
