This product is a viscous assembly lubricant for components and equipment designed to use Skydrol aviation hydraulic fluids. Approved by airframe manufacturers, MCS352B lubricates seals during assembly, preventing them from being damaged. It introduces no foreign material into the hydraulic system because it contains no silicone oils or any petroleum based products. When sliding O-rings over assembly tools, it lubricates the O-ring, enabling it to seat properly without damage. For other assembly tasks where tackiness is required, parts wetted with MCS352B will stick to surfaces long enough to complete an assembly task.
