Low-pressure hose for connection to diving cylinders for underwater activities

1. A low-pressure hose for connection to a diving cylinder for use in underwater activities, the low pressure hose comprising:

an inner tubular element;

an inner sheathing layer directly on the inner tubular member and comprising a polyester braid;

an outer sheathing layer directly on the inner sheathing layer and comprising a nylon braid to define an abrasion-resistant outermost element of the low pressure hose that is independent from, not attached to, and does not cooperate intimately with the inner tubular element and inner sheathing layer and thereby provides enhanced flexibility and kinking prevention; and

a hose coupling extending directly over the outer sheathing layer at an end of the hose for connecting to the diving cylinder.

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

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

4. The low-pressure hose according to claim 1 , wherein said outer sheathing layer further defines a UV protection element.

5. The low-pressure hose according to claim 1 , wherein said hose coupling element comprises at least one of stainless steel and brass.

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

7. The low-pressure hose according to claim 6 , wherein the bursting resistance is at least 250 Bars.

8. The low-pressure hose according to claim 6 , wherein the tensile strength is at least 200 Kg.

9. The low-pressure hose according to claim 1 , wherein the nylon braid of the outer sheathing layer is configured to prevent kinking of the low-pressure hose when bent during underwater diving activities.
