👉 The break fluid, also known as the separator fluid, is a specialized lubricant used in hydraulic systems to facilitate smooth operation and prevent damage between moving parts. It is typically a viscous fluid that separates the hydraulic cylinder or pump from its piston or rod, ensuring minimal friction and wear while allowing for efficient power transmission. Break fluid is specially formulated to maintain its properties under high pressure and temperature conditions, often containing additives to enhance its performance and longevity. Its primary function is to minimize fluid leakage and contamination, ensuring the hydraulic system operates reliably and effectively.
