Stirlings Hydraulic 46 HLP. A high grade EP hydraulic oil based on selected solvent refined base oils having a natural viscosity index, under addition of additives to obtain the following properties:

  • an excellent protection against wear
  • a very good activity against rust and corrosion
  • an excellent stability against oxidation
  • very good demulsification properties
  • very good deaerating and foam-suppressing properties
  • good compatibility with seals and gaskets made from synthetic material
  • low pour point
This type of hydraulic fluid may be used for heavy duty hydraulic equipment, as well as for light duty gear boxes and bearings. This hydraulic oil may also be used for lubrication systems, general lubrication and vacuum pumps (with the exclusion of turbines).
