Abstract: A hose comprises a hose wall comprising a soft synthetic resin and a hard spiral reinforcement fused with or bonded to the hose wall for retaining the hose configuration. The hose wall comprises at least one layer of a chlorine-free thermoplastic elastomer such as a polystyrenic thermoplastic elastomer, a polyolefinic thermoplastic elastomer and a polyurethane-series thermoplastic elastomer. The reinforcement comprises a hard wire and a covering resin layer formed on the hard wire. The hose wall and the covering resin layer are formed with the same series elastomer. This hose is lighter and free from PVC resins, and has the same flexibility as that of the conventional PVC hoses.
