A rubber hose includes a distinctly colored inner wear indicator integrated into its liner, wherein a distance b of the inner wear indicator from the inner surface of the liner is less than 40% of the liner's thickness v, and height h of the wear indicator, measured perpendicularly to a longitudinal axis of the hose, falls between 1% to 90% of liner thickness v, or even from 10% to 40% of the liner thickness v. The inner wear indicator may have concentric sectional surface area of the inner wear indicator may even gradually decrease in the radial direction as a function of distance from the longitudinal axis. The rubber hose may be connected at one end to a plunger pump and connected at a second to a common manifold, in an oilfield pump system, or used in any hose application in an oilfield fluid pump system.
