There are special applications that require the use of non conductive hydraulic hose. Utility bucket trucks, cherry pickers and any application that is near electric lines typically have dielectric hydraulic hose instead of your typical hydraulic hose due to the potentially conductive proerties of your standard wire braid hydraulic hose.
