Applications
AeroShell Fluid 61 is designed for use where a fire-resistant preservative grade hydraulic fluid is required and is suitable for operational use from -40掳C to +204掳C (-40掳F to +399掳F) as well as preservation of components during storage and shipment.
AeroShell Fluid 61 is compatible with AeroShell Fluids 31 and 41 but as a synthetic oil, should not be used in contact with incompatible seal materials.
Chlorinated solvents should not be used for cleaning hydraulic components which use AeroShell Fluid 61. The residual solvent contaminates the hydraulic fluid and may lead to corrosion.
