Castrol Aero 40 is available in two versions: red dyed (Douglas Aircraft) or straw colored (yellow) undyed (Boeing Spec BMS 3- 32, Type II).
Uses :
Castrol Aero 40 is designed for use in landing gear shock struts. It is compatible with approved MIL-PRF-6083 and MIL-PRF-5606 hydraulic fluids. It is not completely compatible with synthetic gas turbine lubricants or with phosphate-ester hydraulic fluids. It is compatible with other petroleum-based and synthesized hydrocarbon lubricants but contamination should be avoided in order to maintain the unique properties of Castrol® Aero 40. This product 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 the appropriate technical support contact.
