R13 hydraulic hose is one of high pressure hose pipe which consists of 4high tensile steel spirals (DN 6-25) and 6 high tensile steel spirals (DN 31-51) for reinforcement ,because the spiral hose has same high working pressure (35Mpa) in all size from 1/4’’ to 2’’.SAE 100R13 hose is suitable for delivering petroleum-based hydraulic lines and mainly used in high pressure working conditions. This spiral hose pipe has Superior abrasion resistance and high ozone and weather resistance.The hydraulic hose is made from oil-resistant synthetic rubber for inner tube, 4 or 6 high tensile steel spirals for reinforcement and Synthetic rubber with high abrasion, ozone, weather and heat resistance for wrapped cover which has high fatigue resistance performance and Superior abrasion resistance high ozone and weather resistance .R13 hydraulic hose meet and exceed the standard of SAE 100R13.…
