Hydraulic Hoses Information


Hydraulic hoses are used in situations in which rigid structures, such as tubes and pipes, cannot be used. The flexibility of hoses makes them ideal for use in hydraulics and pneumatics. The type of hydraulic hose you select will be determined by the type of fluids or gasses you transport, such as fuel oil, hydraulic oil, or mineral oil. Most industries, such as the aerospace, agriculture, mining, and construction industries as well as manufacturing depend on hydraulics in some form. Most hoses are made with an inner lining of oil resistant, synthetic rubber. The layer wrapping the tube is usually made of a high tensile braided or spiraled wire. The outer wrapper protects the wire braid and gives fittings a strong surface to grip. Choosing the proper hose and fittings will ensure that your machines operate properly and that you don’t suffer any downtime due to hydraulic failure. The hoses are graded by three different categories:

  • Pressure
  • Fluid Compatibility
  • Temperature

Machines and vehicles that use hydraulics must operate in extreme conditions. Not only is the work brutal, but environmental factors can take a toll on machinery. Modern equipment is capable of arduous labor, and durable hydraulic hoses and fittings are crucial to uninterrupted work. These hoses must be selected based on both interior and exterior diameter. Operating pressure is considered in the equation, but burst pressure must also be considered. Different hoses have different bending radii, so you have to be careful to choose hoses that will work with your machinery and job site.
