👉 The pad fluid, also known as the pad lubricant or sealant fluid, is a critical component in hydraulic systems that serves to minimize friction and wear between the moving parts of the hydraulic cylinder and its seals, as well as the piston and cylinder walls. It forms a thin, protective layer that ensures smooth operation by reducing direct metal-to-metal contact and dissipating heat generated during hydraulic fluid movement. This fluid is typically a specialized oil with additives designed to enhance its lubricating properties and maintain system integrity under varying temperatures and pressures.
