Abstract
A composite hose for heavy-duty purposes is disclosed which is essentially comprised of a flexible main hose of increased diameter and a subhose disposed longitudinally thereover. The subhose has a reinforcing layer oriented at a specified angle to thereby dilate widthwise upon application of pressure, allowing the main hose to readily bend in a predetermined direction.
