Although the military did not move to phosphate ester type fluids they did identify the need for a more fire resistant fluid as a direct replacement for MIL-H-5606. As a result a synthetic hydrocarbon-based fluid, MIL-H-83282 was developed. This fluid is completely compatible with MIL-H-5606 fluids and MIL-H-5606 hydraulic system materials. All physical properties of MIL-H-83282 (now MIL-PRF-83282) were equivalent to or superior to those of MIL-H-5606 (now MIL-PRF-5606) except for low temperature viscosity. In particular all fire resistant properties of MIL-PRF-83282 are superior to those of MIL-PRF-5606.
What is MIL-H-5606 hydraulic oil?

What is mineral based hydraulic oil?
What is hydraulic oil? Hydraulic oil, also known as hydraulic fluid, is a synthetic (man-made) or mineral-based, non-compressible fluid that is used to transfer power in hydraulic machinery and equipment. At Nationwide Fuels, we supply 99% mineral-based hydraulic oils.
Why is mineral oil called mineral oil?
Mineral oil is any of various colorless, odorless, light mixtures of higher alkanes from a mineral source, particularly a distillate of petroleum, as distinct from usually edible vegetable oils.
Which hydraulic fluid is red?
KLONDIKE Red Hydraulic Fluids are designed for high performance hydraulic systems. These fluids provide excellent operating and maintenance benefits for increased productivity.
Is tractor transmission fluid and hydraulic fluid the same?
Hydraulic oil transfers power, while tractor fluid lubricates the moving parts within a transmission. Choosing the right tractor fluid and hydraulic oil can have an effect on the performance of your equipment.
Can I use ATF instead of hydraulic fluid?
Most hydraulic systems will operate satisfactorily using a variety of fluids. These include engine oil, automatic transmission fluid and oil formulated specifically for the hydraulic compartment.
Is there a difference between hydraulic fluid and hydraulic oil?
Hydraulic Fluid vs Hydraulic Oil Hydraulic fluid is the medium that is useful in energy transferring in hydraulic systems such as excavators, backhoes, hydraulic brakes and garbage trucks. Hydraulic oil is a flammable fluid that is useful in energy transfer in a hydraulic system.
What is phosphate ester hydraulic fluid?
Phosphate esters are the most fire resistant of the non-aqueous synthetic basestocks in common use. Their high ignition temperatures, excellent oxidation stability and very low vapor pressures make them difficult to burn, while their low heats of combustion result in self-extinguishing fluids.
What kind of hydraulic fluid goes in a dump trailer?
Use a good grade of non-foaming hydraulic fluid with anti-corrosion and anti-wear additives such as Napa AW-68 hy- draulic fluid.
What is ISO 15 hydraulic oil?
Hydraulic 15 is part of Crown Oil’s range of premium-grade mineral-based hydraulic oils with good anti-wear properties providing protection in the most demanding of systems while still meeting ISO standards for hydraulic oil. This hydraulic fluid is rust, corrosion and oxidation inhibited.
What type of fluid is used in a hydraulic system?
Three common varieties of hydraulic fluids found on the market today are petroleum-based, water-based and synthetics. Petroleum-based or mineral-based fluids are the most widely used fluids today.
Why is the MIL-H-5606 oil used?
The US Military developed the MIL-H-5606 oil specification to set performance levels for hydraulic fluids they use in aircraft .
What is the MIL 5606?
Most hydraulic applications calling for an oil meeting MIL-H-5606 are land-based hydraulic applications that don’t need to meet the “super clean” requirement. If you’re looking for a land-based 5606 lubricant, there are less costly alternatives, such as Kendall’s Hyken Glacial Blu and Mobil’s Aero HFA.
What does MIL stand for in oil?
MIL stands for Military, H for hydraulic fluid, and 5606 designates oil’s the performance properties.
Why do manufacturers use lubricant?
A lot of equipment manufacturers call for this lubricant as well because it performs so well in cold temperatures.
Is 5606a the same as 5606h?
Exactly as depicted. 5606a is same as 5606h, just gets different suffix once its taken from the original container.
Is 5606A compatible with 5606?
At the very least it supercedes 5606 and is compatible with all appropriate applications.
Is hydraulic fluid doubled by postage?

What is the replacement for MIL-H-5606?
Commonly MIL-H-5606 is replaced with the compatible MIL-H-83282 or now PRF due to its increased flammability resistance. As long as the operating temp range stays above -40. It also is not restricted to piston engine aircraft, Beechcraft King Air with a PT-6 as well as many turbine commercial helicopters use one or both of these fluids. Sikorsky, Bell and Airbus helicopters to name a few.
What is a MIL 5606?
MIL-H-5606 and MIL-PRF-5606 are US specifications for hydraulic fluid based on mineral oil. They are used in US military 3000 PSI hydraulic systems.
Why did the MIL specs change?
The biggest change in MIL specs was to move away from a design or manufacture spec to a performance spec. The downside of the old specs were that they didn’t allow for an improved product without getting the spec revised. By switching to performance spec (what it must do as opposed to how to make it), improvements can be made without spec revisions and contract revisions (that call out the specs) ultimately saving everyone time and money while delivering products that use up to date technology.
Is there a difference between the old 5606 and the replacement 83282?
Visually, there is no distinctive difference between the old 5606 and the replacement variants of 83282.
Why use aeroshell hydraulic fluid?
AeroShell Hydraulic Fluids are widely used in non-aviation applications because of their superior performance, particularly at temperature extremes, when compared with standard industrial hydraulic fluids . Many non-aviation equipment manufacturers do permit use of AeroShell Hydraulic Fluids in their equipment and in many cases list the product in the appropriate manuals. Otherwise in selecting an AeroShell Hydraulic Fluid for a non-aviation application the properties of the hydraulic fluid must be examined. This will only give an approximate indication as to the expected performance in the specific application. However, such data must be regarded as guidance only. There is no laboratory test that can give a complete prediction of performance in actual use, and the final stage in any decision must involve performance tests in either the actual equipment or in the laboratory/test house under conditions expected in service.
What is Aeroshell Fluid 31 used for?
AeroShell Fluid 31 is recommended for use in aircraft, ordnance, and missile systems operating from –40°C to +205°C. This fluid should be considered for use in auto pilots, shock absorbers, brakes, flight control systems, hydraulic servo-controlled systems and other systems using synthetic elastomer seals.
What is AeroShell 61?
