<p>A composite hose for conveying of refrigerant includes an inner surface resin layer 11, an inner tube rubber layer 12, reinforcing layers 13, 15 formed from polyethylene naphthalate filaments, and an outer cover rubber layer 16. By forming the reinforcing layers from polyethylene naphthalate, regardless of whether there is an inner surface resin layer, the composite hose has excellent flexibility, little permeation of refrigerant, excellent heat resistance, excellent durability, and is inexpensive. <IMAGE></p> |
