摘要: The present invention provides a water hose which includes an inner layer and an outer layer that are concentric and tube-shaped, and a reinforcement fiber layer that is formed by interweaving reinforcement fibers between the inner layer and the outer layer. The inner layer and the outer layer are formed by vulcanizing a composition for a hose that includes an ethylene-propylene-nonconjugated diene copolymer and an ethylene-butene-nonconjugated diene copolymer such that a mass ratio (ethylene-propylene-nonconjugated diene copolymer/ethylene-butene-nonconjugated diene copolymer) is 80/20 to 30/70. A Mooney viscosity (ML (1+4) 100° C.) of the ethylene-butene-nonconjugated diene copolymer is lower than a Mooney viscosity (ML (1+4) 100° C.) of the ethylene-propylene-nonconjugated diene copolymer.
