👉 The handle fluid, also known as a lubricant or sealant, is a specialized substance applied to the ends of moving parts in mechanical systems to reduce friction and wear. It acts as a protective barrier, preventing direct metal-to-metal contact and minimizing heat generation. This fluid typically contains additives that enhance its lubricating properties, such as viscosity modifiers and anti-wear agents. By maintaining a smooth operation, handle fluid extends the lifespan of machinery and ensures efficient performance while reducing energy consumption and noise.
