Abstract

A hose assembly, preferably a garden hose assembly, including a jacketed tube that is lightweight, durable and versatile. The tube is able to expand longitudinally along the length-wise axis of the hose between hose ends, as well as radially or circumferentially, to an expanded state in response to application of at least a minimum fluid pressure to an inner tube of the hose. Once the fluid pressure falls below the minimum fluid pressure, the hose assembly will contract. The two layer construction of the hose assembly allows for storage in relatively compact spaces, similar flow rates, approximately one-half the weight, and improved maneuverability when compared to conventional hose constructions. In one embodiment the jacket is formed around the tube in a continuous process that welds a material, preferably using hot air, into the jacket. The welded joint forms a region of jacket that is preferably about twice the thickness of the rest of the jacket. This thicker region results in a stiffer section of jacket that makes the hose more controllable and consistent in use.
