Hydraulic hoses are far more important components of machinery, equipment and industries. There are standard hydraulic hoses which are produced depending on SAE R100, EN 853, EN 856 and so on. Their reinforcements are one steel wire reinforcement, two steel wire reinforcement, three steel wire layers, four steel wire layers and six steel wire layers. However, standard rubber hoses can’t meet all specified requirements. Hence, special hydraulic hoses which are designed with high pressure or smaller bending radius is supplied.
