<p>PURPOSE:To develop a long-lived wear resisting hose having excellent wear resistance and high rigidity and bending performance (kink resistance). CONSTITUTION:In a hose having at least a rubber inner tube 2, an intermediate reinforcing layer 7, a rubber outer tube 6, and an ultra-high molecular polyethylene layer 1 having a weight average molecular weight of 1,000,000-2,000,000 provided on the most inside layer, the ultra-high molecular weight polyethylene layer 1 is integrally provided with the rubber inner tube 2, and the thickness (t) (mm) of the ultra-high molecular weight polyethylene layer 1 and the hose inner diameter D (mm) have a relation of 7.7X10<-4>D<=t<=6.1X10<-2>D.</p> |
