MCS352B Assembly Lubricant

MCS 352B is an assembly lubricant compatible with Skydrol hydraulic fluid systems. It is a thick, viscous liquid that has two uses:
  1. When sliding O-rings over assembly tools, it lubricates the O-ring, enabling it to seat properly without damage.
  2. For other assembly tasks where tackiness is required, parts wetted with MCS-352B will stick to surfaces long enough to complete an assembly task.

MCS-352B is the only lubricant approved for use in phosphate ester hydraulic systems. It contains chemical components that are actual ingredients used in Skydrol hydraulic fluids. By using MCS 352B for assembly, there is no foreign contamination introduced into the hydraulic fluid.
