Disclosed is a flexible plastic hose (1) comprising a tubular hose body (2) having web portions (7) and a helical reinforcing rib (8), and a cuff (3a) mounted to an extremity (16) of the hose body (2) comprising a molded end fitting (5a) bonded to the extremity (16a), and a stress relief element (4) with a first segment (S1) having an internal screw-thread (15) complementary to the helical reinforcing rib (8). Disclosed is also a method for making same, and use of the hose (1) as a medical hose.

A method for production of a tubular body applying the following steps: Pressureless application of at least one first curable plastic layer made of reactive polyurethane materials with a core via a rotational molding process, Curing the at least one plastic layer, Winding at least one reinforcement layer onto the at least one first plastic layer, Pressureless application of at least one second curable plastic layer, wherein the reinforcement layer is embedded without holes between the two plastic layers, and Removal of the core after completion of the body.

Because of this, the position of the reinforcement layer 7 can be individually established and it can be ensured that the reinforcement layer will not penetrate into the first plastic layer during winding after the curing of the first plastic layer.

A flexible duct includes a hollow tube shape, at least one end, a first circumferential attachment and a second circumferential attachment integral to the at least one end, wherein the first circumferential attachment and the second circumferential attachment are each configured to independently mechanically couple the at least one end around a first inlet or a first outlet, and wherein the first circumferential attachment and the second circumferential attachment are different. A method includes providing a flexible duct, selecting one of the first circumferential attachment or second circumferential attachment of the flexible duct, and mechanically coupling the selected first circumferential attachment or second circumferential attachment around the first inlet or first outlet. A connector for a flexible duct includes a hollow tube shape extending between a first connector end and a second connector end and a first circumferential attachment and second circumferential attachment integral to the at least one end.

A multilayer tube which includes, in succession from inside outward: an inner layer constituted by a tubular sheath which defines a passage duct for a fluid and is corrugated at least externally, thus defining troughs, a protective layer for the inner layer and which follows its corrugated shape, and a helix wound on the protective layer and positioned on a bottom of the troughs, and an outer layer, in which the helix is embedded.

Hemp fibers may be disposed throughout or in selected portions of a hose (e.g., an expandable water hose). The hemp fibers deployed in the hose enhance the durability of the hose, and imparts various advantageous properties (e.g., anti-microbial or anti-bacterial, mildew-resistant, odor reduction, moisture wicking, etc.) to the hose.
