Polymer spirals protect the high-pressure hose from mechanical wear and significantly increase the service life of the RVD. Materials – high-density polymers have a slippery surface and withstand contact without destruction even with sharp objects.

Plastic spiral protection is easily installed without removing the hydraulic hose from the equipment.

Plastic protection for RVD in the form of a spiral of large diameters is used when assembling a set of RVD and cables into a single bundle, which reduces the cost; laying and operation of harnesses on equipment.

Compared to a steel spiral, damage to the outer shell of hoses and cables is significantly reduced, operating costs are reduced by up to 90%.
