👉 Protection fluid, also known as sealant or lubricant fluid, is a specialized lubricant used in various mechanical systems to reduce friction and wear between moving parts. It forms a thin, protective layer on metal surfaces, minimizing direct contact and heat generation, which enhances the longevity and efficiency of components such as bearings, gears, and engine parts. This fluid is typically applied during assembly or maintenance to ensure smooth operation and prevent premature wear, corrosion, and other forms of mechanical degradation. Its composition often includes additives that provide additional benefits like anti-wear properties, corrosion resistance, and thermal stability, making it an essential component in maintaining the optimal performance of mechanical systems.
