Hydraulic oil properties of the sealing member

Hydraulic oil for hydraulic drive system as the working medium, from the energy transfer, conversion and control role, while also playing the various components within the hydraulic system for lubrication, corrosion, rust and cooling effect. The hydraulic system plays a seal to prevent leakage of fluid from the joint surfaces, maintaining the pressure, to maintain the role of energy transfer or conversion.Jic hydraulic fittings  oil for hydraulic drive system as the working medium, from the energy tansfer, conversion and control role, while also playing the various components within the hydraulic system for lubrication, corrosion, rust and cooling effect.
