Abstract: 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.

Abstract: A brake hose has an inner rubber layer, an outer rubber layer, and at least two reinforcing layers provided between the inner rubber layer and the outer rubber layer. The reinforcing layers include an upper yarn layer, and a lower yarn layer. Polyester yarn having a tensile strength of not lower than 6.9 g per unit dtex and having a stretchability of 2.6±1.0% at 2.7 g load per unit dtex is used as lower yarn in the lower yarn layer. The braid angle of the lower yarn layer with respect to the axial direction of the hose is set at 59±2°.
