👉 The inserted fluid, often referred to as a lubricant or sealant, is a substance added to a system to reduce friction between moving parts and enhance durability. It typically consists of oils, greases, or specialized polymers that create a protective layer, preventing direct metal-to-metal contact and minimizing wear. This fluid is crucial in applications like engines, hydraulic systems, and mechanical joints, where it helps maintain smooth operation, prolongs component life, and ensures efficient performance by reducing energy loss due to friction.
