Abstract

A low-pressure hose for connection to diving cylinders for underwater activities, comprising an inner tubular element, which is sheathed by an inner sheathing layer constituted by a polyester braid, the hose further comprising an outer sheathing layer constituted by nylon braiding.

Claims

1. A low-pressure hose for connection to diving cylinders for underwater activities, comprising an inner tubular element, which is sheathed by an inner sheathing layer constituted by a polyester braid, further comprising an outer sheathing layer constituted by nylon braiding.

2. The low-pressure hose according to claim 1, wherein said inner tubular element is made of polyethylene.

3. The low-pressure hose according to claim 1, wherein said inner tubular element is made of polyurethane.

4. The low-pressure hose according to claim 1, wherein said outer sheathing layer is provided directly on said inner tubular element.

5. The low-pressure hose according to claim 1, wherein said outer sheathing layer is kept stable by coupling with rings or bushes which form connecting elements of said hose.

6. The low-pressure hose according to claim 1, wherein said outer sheathing layer is adapted to increase bursting resistance and tensile strength of the hose.
