Why is Mack 19 Oil for Mechanical Vacuum Pumps Superior To Competitive Brand Products?
*Higher Molecular Weight = less backstreaming
*Higher Viscosity Index = greater thermal stability
*Less Than 0.01% Sulfur = higher purity
We had an independent testing laboratory perform a modified RBOT D-2272 test to determine the oxidative stability of Mack 19 compared to Inland 19®. This test employs a method to achieve rapid oxidation of the lubricant tested and then measure the degradation characteristics of the oil.
In the test results, Mack 19 lasted longer than the Inland 19® -it also exhibited less viscosity change and less sediment weight at the conclusion of the test.
Buy Mack 19 for longer pump life and better performance.
