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.
Designed to meet the demanding requirements of aviation applications, AeroShell Fluid 31 offers excellent anti-wear and anti-corrosion properties. This aviation hydraulic fluid helps reduce friction and wear on hydraulic components, extending their lifespan and ensuring smooth operation.
This aviation hydraulic fluid also has exceptional thermal stability, allowing it to maintain its viscosity and lubricating properties even under high temperatures. This aviation hydraulic fluid effectively protects against oxidation and deposit formation, preventing system failures and maintaining optimal performance.
AeroShell Fluid 31 is compatible with a wide range of aircraft hydraulic systems, making this aviation hydraulic fluid a versatile choice for many aircraft models. Its high-quality formulation meets the stringent standards set by major engine and aircraft manufacturers.
By choosing AeroShell Fluid 31, you can have confidence in the reliability and efficiency of your aircraft's hydraulic system. Its superior lubrication and protection properties help ensure safe and smooth operation, making it an excellent choice for aviation applications. Order aircraft 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.
