AEROSHELL FLUID 41194Hydraulic FluidsAero<strong>Shell</strong> Fluid 41 is a mineral hydraulic oil manufactured to a very highlevel of cleanliness, and possesses improved fluid properties. Aero<strong>Shell</strong>Fluid 41 contains additives which provide excellent low temperature fluidityas well as exceptional anti-wear, oxidation - corrosion inhibition and shearstability. In addition metal de-activators and foam inhibitors are included inthis high viscosity index fluid to enhance performance in hydraulicapplications. Aero<strong>Shell</strong> Fluid 41 is capable of wide temperature rangeoperation.Aero<strong>Shell</strong> Fluid 41 is dyed red.APPLICATIONSAero<strong>Shell</strong> Fluid 41 is intended as a hydraulic fluid in all modern aircraftapplications requiring a mineral hydraulic fluid. Aero<strong>Shell</strong> Fluid 41 isparticularly recommended where use of a "superclean" fluid can contributeto improvements in component reliability, and can be used in aircraftsystems operating unpressurised between –54°C to 90°C and pressurisedbetween –54°C to 135°C.Aero<strong>Shell</strong> Fluid 41 should be used in systems with synthetic rubbercomponents and must not be used in systems incorporating natural rubber.Refer to the General Notes at the front of this section for furtherinformation.Aero<strong>Shell</strong> Fluid 41 is compatible with Aero<strong>Shell</strong> Fluids 4, 31, 51, 61 and71 and SSF/LGF.Chlorinated solvents should not be used for cleaning hydraulic componentswhich use Aero<strong>Shell</strong> Fluid 41. The residual solvent contaminates thehydraulic fluid and may lead to corrosion.SPECIFICATIONSU.S.BritishApproved MIL-PRF-5606H*(both U.S. and European production)Approved DEF STAN 91-48 GradeSuperclean* (European productiononly)Meets DEF STAN 91-48 GradeNormal (European production only)Equivalent to DEF STAN 91-48Grades Superclean* & Normal(U.S. production only)French Approved DCSEA 415/ARussianNATO CodeJoint Service Designation*Superclean gradesAnalogue to AMG-10H-515* (equivalent H-520)OM-15* (equivalent OM-18)The British specification DEF STAN 91-48 covers two grades (normal andsuperclean) of mineral hydraulic fluid which differ only in their cleanlinesslimits. Aero<strong>Shell</strong> Fluid 41 is manufactured to meet the supercleanrequirements and thus it also meets the requirements of the normal grade.Hydraulic Fluids195www.shell.com/aviationThe Aero<strong>Shell</strong> BookEdition 18 2003
