Features of Aero 40:

  • Approved EP additive
  • Reduces martensitic streaking of landing gear outer cylinders and galling of shock strut upper bearings.


Castrol Aero 40 is designed for use in landing gear shock struts. Castrol Aero 40 is compatible with approved MIL-PRF-6083 and other MIL-PRF-5606 qualified hydraulic fluids. It is not completely compatible with synthetic gas turbine lubricants nor with phosphate-ester hydraulic fluids. It is compatible with other petroleum-based and synthesised hydrocarbon lubricants but contamination should be avoided in order to maintain the unique properties of Castrol Aero 40. It is compatible with seals, hoses and paints normally used in shock struts and dispensing equipment connected with this application. While certain grades of the above materials are fully compatible with Castrol Aero 40, it is advisable to confirm acceptability of use with either the material manufacturer or Castrol.
