👉 A letting fluid, often found in the context of hydraulic systems, is a liquid that acts as a carrier for gases or other substances within these systems. It's typically used to introduce and circulate gases like air, nitrogen, or oxygen into hydraulic fluids. This fluid helps in lubricating moving parts, reducing friction, and enhancing the overall performance and longevity of hydraulic machinery. By allowing gases to mix with the fluid, letting fluids ensure that the hydraulic system operates efficiently and effectively.
