ABSTRACT:
Disclosed is a pressure-resistance hose having a watertight structure capable of preventing a due condensation phenomenon, called a sweating phenomenon, from occurring on an exposed end or a surface of the pressure-resistance hose by coating adhesives on both overlapping ends of the pressure-resistance hose including polyethylene mixed fabrics and a watertight film coated on upper and lower surfaces of the polyethylene mixed fabrics in such a manner that the polyethylene mixed fabrics exposed along an end portion of the pressure-resistance hose are covered with adhesives. The reliability and endurance of the pressure-resistance hose are improved, thereby achieving a high value-added pressure-resistance hose.
