An increasing number of aircraft manufacturers now recommend use of this type of aviation hydraulic fluid in aircraft hydraulic systems in preference to mineral hydraulic oils. This move has been prompted by the need to use fluids with better fire resistant properties.
AeroShell Fluid 31 provides excellent anti-wear and anti-corrosion properties, reducing friction and extending the lifespan of hydraulic components. This results in improved reliability and efficiency of the aircraft's hydraulic system.
AeroShell Fluid 31 offers exceptional thermal stability. This aviation hydraulic fluid maintains its viscosity and lubricating properties even under high temperature conditions, preventing viscosity breakdown and ensuring consistent performance.
Furthermore, this aviation hydraulic fluid resists oxidation and deposit formation, preventing system failures and maintaining the cleanliness of the hydraulic system.
AeroShell Fluid 31 is compatible with a wide range of aircraft hydraulic systems, making this aircraft supply a versatile choice for various aircraft models. This ensures convenience and ease of use, along with the confidence in its ability to meet the stringent standards set by major engine and aircraft manufacturers.
Choosing AeroShell Fluid 31 means choosing a reliable aviation hydraulic fluid that delivers superior performance, protection, and compatibility, making this aircraft supply an excellent option for aviation applications. Order aircraft maintenance supplies today.
Approvals & Use Approved under MIL-PRF-83282D
AeroShell Fluid 31 is also approved for use in the Honeywell (formerly Garrett) cooling turbine (cabin air compressors). AeroShell Fluid 31 is compatible with AeroShell Fluids 4, 41, 51, 61 and 71 and can be used in systems designed to operate with MIL-PRF-5606, MIL-PRF-6083, MIL-PRF-87257 and MIL-PRF-46170 fluids.
Chlorinated solvents should not be used for cleaning hydraulic components which use AeroShell Fluid 31. The residual solvent contaminates the hydraulic fluid and may lead to corrosion. AeroShell Fluid 31 is a synthetic hydrocarbon oil and should not be used in contact with incompatible seal material.
Compatibility
Mineral hydraulic fluids (MIL-PRF-5606, MIL-PRF-6083) are completely compatible and miscible with synthetic hydrocarbon hydraulic fluids (MIL-PRF-83282, MIL-PRF-87257 and MIL-PRF-46170) and vice versa. Mineral hydraulic fluids (MIL-PRF-5606 and MIL-PRF-6083) and synthetic hydrocarbon hydraulic fluids (MIL-PRF-83282, MIL-PRF-87257 and MIL-PRF-46170) are not compatible with phosphate ester hydraulic fluids and on no account should they be mixed.
Changeover from MIL-H-5606
Since mineral hydraulic fluids are compatible with synthetic hydrocarbon fluids changeover can be easily accomplished. Two commonly used methods to convert existing MIL-H-5606 based hydraulic systems to MIL-PRF-83282 have been:
(1) draining the aircrafts hydraulic system or the hydraulic system reservoir of MIL-PRF-5606 and refilling with MIL-PRF-83282, thereafter servicing the aircrafts hydraulic system with MIL-PRF-83282 and (2) merely topping off the reservoir with MIL-PRF-83282, as needed. Both methods have been used with great success with no reported problems.
