👉 A locking fluid is a specialized lubricant used in mechanical systems, particularly in hydraulic and pneumatic applications, to prevent metal-to-metal contact between moving parts. It achieves this by creating a thin, protective film that adheres to the surfaces, even under high pressure and temperature conditions. This fluid is designed to be highly resistant to shear and oxidation, ensuring long-lasting protection and maintaining system efficiency. When a component moves within the fluid, it forms a seal that locks the parts together, preventing leaks and wear. Common examples of locking fluids include silicone-based, polyurethane, and fluorocarbon formulations, each chosen for specific performance characteristics such as temperature range, chemical resistance, and compatibility with system materials.
