👉 A lock fluid, also known as hydraulic fluid, is a specialized liquid used in hydraulic systems to transmit power and control mechanical movements. It operates by circulating through a network of pipes and cylinders, where it fills the chambers of hydraulic motors, valves, and actuators. When pressurized, the fluid exerts force on these components, enabling precise and powerful control of machinery. Lock fluids are engineered to have specific properties such as high viscosity, low volatility, and excellent lubrication capabilities to ensure efficient operation, durability, and safety in various industrial applications, from construction equipment to aerospace systems.
