PROBLEM TO BE SOLVED: To provide a liquid hose using an elastomer containing no halogen-containing compound, particularly free from odor transfer to water and colored water (black water) and superior in lighter weight, flexibility, heat resistance, durability and fitting assembling efficiency. SOLUTION: The liquid hose comprises an inner layer 1 as an inside layer using an olefinic thermoplastic elastomer (TPO) consisting of polypropylene (PP) and an ethylene propylene diene rubber (EPDM), a reinforcing layer provided on the outer peripheral face of the inner layer 1 in a braided or wound manner, and an outer layer 3 as an outside layer using a dynamic cross-linked olefinic thermoplastic elastomer (TPV) that a completely or partially cross-linked ethylene propylene diene rubber (EPDM) of 5μm or shorter is dispersed into a polypropylene (PP) matrix (continuous layer). The inner layer and the outer layer are directly fused together via the reinforcing layer. The reinforcing layer preferably has a braiding or winding angle of 45-60°. COPYRIGHT: (C)2006,JPO&NCIPI
