Abstract
The present invention provides for a light weight, thin walled hose which is rigid enough to resist kinking at low pressures. The hose includes a generally circular woven inner jacket reinforcement layer; an extruded inner tubing bonded to the inner surface of the inner jacket; a circular woven outer jacket reinforcement layer; and an intermediate tubing bonded to the inner surface of the outer jacket and located between the inner and outer jackets. The intermediate tubing adds thickness to the overall wall of the hose, and stiffens the outer jacket sufficiently so that it resists kinking.
