👉 Manual fluid, often referred to as "manual lubricant" or "lubricating oil," is a specialized type of lubricant designed to reduce friction and wear in mechanical systems when they are not under operational pressure or when hydraulic systems are not active. It is typically used in applications such as pumps, valves, and bearings to ensure smooth operation and extend the lifespan of moving parts. Unlike hydraulic fluids, manual fluid does not need to maintain a constant pressure and is usually applied in small quantities directly to the components it needs lubrication. This fluid is crucial in environments where water contamination or high-pressure systems are not feasible, providing essential protection against corrosion and mechanical failure.
