Aviation Hydraulic Fluids and Preservatives
Keep your aircraft hydraulics moving and components preserved for longer with the AeroShell range of aviation hydraulic fluids and preservatives. Each of our fluids serves a much-needed purpose within today’s aviation needs, from calibration and preservation to hydraulic use. They meet a variety of specifications, including MIL-SPECs, and offer a high-quality option whenever these specifications must be met.
Mineral hydraulic fluids
AeroShell Fluid 41
- Super clean mineral hydraulic fluid.
- Approved to MIL-PRF-5606.
AeroShell Fluid 41 is a mineral hydraulic oil manufactured to a very high level of cleanliness and it possesses improved fluid properties.
It contains additives that provide excellent low-temperature fluidity as well as exceptional anti-wear, oxidation – corrosion inhibition and shear stability. In addition, metal de-activators and foam inhibitors are included in this high-viscosity index fluid to enhance performance in hydraulic applications.
AeroShell Fluid 41 is dyed red.
AeroShell Landing Gear Fluid
- Extreme pressure operational hydraulic fluid;
- Based on AeroShell Fluid 41 which already provides strong oxidation stability and anti-wear performance; and
- Approved to BMS 3-32 Type 2.
AeroShell Landing Gear Fluid (LGF) is a mineral hydraulic fluid (MIL-PRF-5606) to which additional additives have been added to improve the extreme pressure characteristics and the fluid’s natural lubricity. The lubricity agent provides a stable thin film layer to the metal surfaces at mild operating conditions. When severe conditions exist (landing/touchdown), the extreme pressure additive supplies the load carrying needed at the metal-to-metal surfaces to prevent the occurrence of such phenomena as ‘ladder cracking’ and ‘slip stiction’ of the piston component of the landing gear.
AeroShell LGF is dyed yellow.
Synthetic hydrocarbon hydraulic fluids
AeroShell Fluid 31
-
- Super-clean, fire-resistant, synthetic hydrocarbon hydraulic fluid.
- Approved to MIL-PRF-83282.
AeroShell Fluid 31 is a synthetic hydrocarbon-based aircraft hydraulic fluid with greatly improved fire resistance characteristics. AeroShell Fluid 31 has a specially designed base stock that imparts a relatively high flash point, excellent low-temperature properties and good oxidation and thermal stability. In addition, AeroShell Fluid 31 is formulated with high-technology additives to provide oxidation and corrosion resistance, anti-wear and anti-foaming protection. AeroShell Fluid 31 is superclean filtered to ensure optimum performance in particulate monitored systems.
AeroShell Fluid 31 is dyed red.
AeroShell Fluid 61
-
- Preservative, synthetic hydrocarbon hydraulic fluid.
- Approved to MIL-PRF-46170 Type 1.
AeroShell Fluid 61 is a synthetic hydrocarbon base hydraulic fluid specifically inhibited to provide excellent oxidation stability for the oil and good corrosion preventive protection to the hydraulic system.
