The core feature of this hose is its exceptional resistance to high pressure and pulsation.The steel wire reinforcement provides very high burst pressure,ensuring safe operation in dynamic high-pressure environments.The cover typically offers excellent abrasion,weather,and oil resistance,suitable for harsh outdoor conditions.The inner tube is optimized for compatibility with hydraulic oil,preventing swelling,cracking,or softening caused by oil degradation.Its flexible design also facilitates routing in complex equipment spaces.
Conforms to international standards like SAE J517(Society of Automotive Engineers)or EN 856(European Standard).Common specifications include 1SN(one steel wire braid,medium pressure),2SN(two steel wire braids,medium-high pressure),R12/13(two steel wire spirals,high pressure),and R15(four steel wire spirals,very high pressure).Inner diameter dimensions are precise to ensure flow rate and system efficiency.Parameters like outer diameter,wall thickness,minimum bend radius,and working pressure are strictly defined.Hoses should be selected with a working pressure rating of at least 1.5 times the system's maximum operating pressure.
Widely used in heavy machinery requiring power transmission,such as excavators,loaders,cranes,and injection molding machines.Also common in mining machinery,agricultural equipment,port machinery,and steel plant hydraulic lines.Essential anywhere significant force and torque are generated via hydraulic oil.
