BM-4 Oil (20L).
vacuum oil
Description
Vacuum oil VM-4 represents the residue after removal of the head fraction from the raw materials by vacuum distillation and has a relatively wide fractional composition. Comes in cans from 5 to 20 liters, 208 liters drums.
Applications
Vacuum oil VM-4 working liquid and seal for the piston fore pumps. BM-4 vacuum oil is produced from high quality mineral base oils differs narrow fractional composition, low volatility and high stability to oxidation.
