Complete documentation
Manufacturer's description
AeroShell Fluid 71 is a preservative mineral hydraulic fluid of improved cleanliness. AeroShell Fluid 71 is composed of a mineral base oil with an additive package which results in a product with excellent corrosion preventative properties as well as excellent oxidation stability, and good anti-wear characteristics.
Applications
- AeroShell Fluid 71 is intended for preserving hydraulic equipment in storage and also for use in rig testing of hydraulic components. AeroShell Fluid 71 should only be used in hydraulic systems employing synthetic rubber seals suitable for MIL- PRF-5606/DEF STAN 91-48 (AeroShell Fluids 4 or 41) type of fluids. AeroShell Fluid 71 is compatible with AeroShell Fluids 4, 31, 41, 51 and 61. Chlorinated solvents should not be used for cleaning hydraulic components which use AeroShell Fluid 71. The residual solvent contaminates the hydraulic fluid and may lead to corrosion.
