What color is HyJet?
Used HyJet IV-A in satisfactory condition may be expected to range in color from blue-purple to red-purple to red to amber. The exposure of HyJet IV-A to air through external leaks, fluid drippings around container openings, etc. will produce a golden or brown color.
What is HyJet?
Mobil HyJet V is a Type V fire-resistant phosphate ester hydraulic fluid, which is superior in thermal and hydrolytic stability to commercially available Type IV hydraulic fluids.
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.
Is skydrol corrosive?
The phosphate ester hydraulic fluids (Skydrol and Hyjet) used on civil aircraft can undergo a hydrolytic decomposition at temperatures above about 300F (150C) in the presence of moisture, producing phosphoric acid that can cause corrosion and hydrogen absorption in titanium alloys.
Why is aircraft hydraulic fluid red?
Mineral-based hydraulic fluid (MIL–H-5606) is processed from petroleum. It has an odor similar to penetrating oil and is dyed red. Synthetic rubber seals are used with petroleum-based fluids.
Why is skydrol purple?
Skydrol is made of a fire-resistant phosphate ester base stock, with a number of oil additives dissolved into it to inhibit corrosion and prevent erosion damage to servo valves. It also includes a purple or green dye to ease identification.
What fluids airplanes use?
Phosphate ester-based Fluids are most widely used in civil transport category aircraft….Hydraulic Fluid for Aircraft.

Which seal material is used with phosphate ester base hydraulic fluids?
87 (8472) – Which seal/material is used with phosphate ester base hydraulic fluids? B- Butyl rubber.
What to do if you get Skydrol on your skin?
Gloves and goggles are recommended safety equipment when servicing Skydrol systems. If the fluid gets on the skin it creates an itchy, red rash with a persistent burning sensation. The effects subside within a few hours; egg white can be applied to the affected area to neutralize the burning.
What is hyjet V used for?
Mobil HyJet V is designed for use in commercial aircraft phosphate ester hydraulic systems. It meets the SAE AS1241 requirements and is included in commercial and business airframe manufacturer Qualified Products Lists, as shown below.
What is hyjet V fire resistant type V hydraulic fluid?
HyJet V fire-resistant Type V hydraulic fluid offers wear and corrosion protection and long service life to meet demanding industry needs. HyJet V from ExxonMobil is a new fire-resistant Type V phosphate ester hydraulic fluid.
What type of hydraulic fluid is Mobil hyjet V compatible with?
It is compatible in all proportions with commercial Type IV and Type V phosphate ester aviation hydraulic fluids. Specifications and Approvals Mobil HyJet V Meets
What is the shelf life of hyjet V?
The shelf life of an unopened container of HyJet V is five years for drums and pails and 10 years for quarts and gallon cans, if it has been stored properly. Based on available toxicological information, HyJet V is not expected to produce adverse effects on health when used and handled properly.
