Hose with metal fitting

Abstract

A hose with a metal fitting includes a hose; a metal fitting including a metal-fitting cylindrical portion to which one end portion of the hose is connected; and a sleeve covering the hose and the metal-fitting cylindrical portion. The inside of the hose communicates with the inside of the metal fitting. The hose includes an inner-surface resin layer, a metal-wire reinforced layer, and an outer-surface resin layer which are lined up in order from the inner side of the hose. The inner-surface resin layer is formed of a single layer containing fluororesin. The sleeve includes a first cylindrical portion covering the metal-fitting cylindrical portion; and a second cylindrical portion which directly covers the hose and which is smaller in diameter than the first cylindrical portion. The length of the second cylindrical portion is 8 mm or more. The thickness of the second cylindrical portion is 1 mm or more. The hardness of the second cylindrical portion is measured in compliance with JISK6253 by Durometer Type A and is 70 or more and 95 or less. A material of the sleeve is thermoplastic elastomer or rubber. The material of the sleeve is the same as a material of the outer-surface resin layer.
