Castrol Aero 35 Yellow Hydraulic Fluid

The product contains a shear stable viscosity index improver, anti-oxidant and an approved EP additive system which reduces martensitic streaking of landing gear outer cylinders and galling of shock strut upper bearings.

It is not completely compatible with synthetic gas turbine lubricants or with phosphate-ester hydraulic fluids. However it is compatible with other petroleum-based and synthesized hydrocarbon lubricants, but contamination should be avoided to maintain the unique properties of its formulation.

This product is compatible with most 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 Aero 35, it is advisable to confirm the acceptability of use with either the material manufacturer or Castrol.
