👉 Socket fluid, also known as socket lubricant or socket grease, is a specialized lubricant designed to reduce friction and wear between moving parts, particularly in mechanical joints like those found in hydraulic cylinders, gearboxes, and other machinery. It is typically a viscous fluid with additives that enhance its performance under extreme conditions, such as high temperatures and pressures. When applied to the socket or bearing surfaces, socket fluid creates a protective layer that minimizes metal-to-metal contact, ensuring smooth operation and extending the lifespan of the equipment. This fluid is crucial for maintaining optimal performance and preventing premature wear or failure in critical mechanical systems.
