ABSTRACT:
A functional pressure hose for a water-carrying system, particularly for connecting movable sanitary fittings or for connecting parts of the water-carrying system with one another, has an inner hose made of plastic and an outer jacket made of a braided material. At least one hose end is provided with a connector piece having a tubular connector, onto which the hose end is pressed. The inner hose is formed by a corrugated hose, and the tubular connector has circumferential ring beads that are adapted to the inner contour of the corrugated hose. At least some of the ring beads are provided with notches that run axially. The hose demonstrates great flexibility while maintaining the required pressure strength, but at the same time guarantees great bending protection.
