Abstract
A pressure hose (1) for a water-carrying system is shown and described, especially for connecting sanitary taps or for connecting parts of the water-carrying system, having a corrugated inner hose (2) made of plastic, wherein at least one hose end (3, 5) of the pressure hose (1) is provided with a connecting piece (4, 6), designed such that it differs from the inner hose (2), for joining the pressure hose (1) to a complementarily designed connecting piece of a sanitary tap and/or a part of the water-carrying system. According to the invention, it is provided that the inner hose (2) and the connecting piece (4, 6) are formed as one piece and the inner hose (2) and the connecting piece (4, 6) are preferably produced via extrusion in a common extrusion process.
Claims8
A pressure hose adapted for a water-carrying system for connecting sanitary taps, comprising:
- a hose portion made of plastic,
- a first connecting piece provided at an end of the pressure hose, the first connecting piece differing in shape from the hose portion,
- a second connecting piece provided at an opposite end of the pressure hose, the second connecting piece having a different shape than the hose portion and the first connecting piece, and
- first and second sealing elements,
- wherein the hose portion and the first and second connecting piece are one monolithic element of one material,
- wherein the second connecting piece comprises at an end face a receiving region on which the second sealing element is received,
- wherein the second connecting piece has on a circumference at least one radially protruding shoulder, the shoulder forming an axial end stop for a tightening element, wherein the shoulder is arranged between the receiving region and second sealing element on one side and the hose portion on an opposite side,
- wherein the first connecting piece comprises an encircling groove on a circumference in which the first sealing element is received, and
- wherein the first connecting piece does not include a shoulder that is configured to enable axial insertion into a complementary connecting piece.
