Overview

ZINC-FREE ANTIWEAR HYDRAULIC FLUIDS FOR AEROSPACE & INDUSTRIAL APPLICATIONS

Phillips 66® X/C 5606J and X/C 5606A Aviation Hydraulic Fluids are mineral oil-based, high viscosity index, ashless (zinc-free) antiwear hydraulic fluids designed to meet the severe demands of aerospace and industrial applications. They have excellent oxidation resistance and outstanding low-temperature properties for use over a wide temperature range. They provide excellent wear protection for hydraulic pumps and motors, protect hydraulic system components against rust and corrosion, and are resistant to excessive foam buildup that can cause poor or sluggish hydraulic system response.

C 5606J Aviation Hydraulic Fluid meets the cleanliness requirements for "super clean" hydraulic fluid for use in modern aircraft hydraulic systems. X/C 5606A Aviation Hydraulic Fluid is recommended for use in hydraulic systems that do not require a "super clean" fluid. Both fluids are dyed red for identification and leak detection purposes.

Features

  • Very high viscosity index for use over a wide temperature range
  • Outstanding low-temperature properties
  • Excellent wear protection
  • Resists deposit formation and viscosity increase due to oxidation
  • Protects against rust and corrosion
  • Good foam resistance
  • Does not contain zinc or other heavy metals

Applications

  • X/C Aviation Hydraulic Fluids are recommended for use in non-pressurized systems operating between –54°C and 90°C (-65°F to 194°F), and in pressurized systems operating between –54°C and 135°C (-65°F to 275°F) at pressures up to 3,000 psi.(1) Typical applications include:
  • Aircraft and missile control systems, autopilots and shock absorbers
  • Auto wreckers, boom trucks and electrical service equipment (cherry pickers) where all-weather performance is required
  • Industrial robotics
  • Hydraulic systems that require a “super clean” fluid for extended service life and reliability (X/C 5606J)
  • (1)Note: Do not use these fluids in hydraulic systems with natural rubber elastomers.

Good hydraulic fluid at a good price. I just wish this came in a plastic bottle with a cap like automotive hydraulic fluid. After all how many general aviation airplane owners need a whole quart to fill up their brakes and nose gear dampener.

Wow. Fast service and the often dented cans were packaged well and arrived undamaged. This is a real success story in a difficult time! Good Job Aircraft Spruce!

After a lot of cross referencing, I found this fluid was compatible with the hydraulic fluid for the lift gate on my wife’s Cadillac SRX. I needed fluid to top off the pump after replacing the lift strut. GM branded fluid was $40 a quart and this was $8. Aircraft Spruce shipped it right away and I actually got the fluid before the arm arrived. Great service, pricing, and super fast shipping. Thanks!

Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: How many litres of Phillips MIL-PRF-5606H hydraulic fluid in a QUART / in a CASE?

On quart is approximately 0.946 Liters. Each case has 24 quarts. So the approximate liters in a case is 22.27 liters.

Q: Is the PHILLIPS 66 X/C MIL-PRF-5606H HYDRAULIC FLUID considered a hazardous shipping item?

No, this is not considered hazardous material.

Q: Is Mil-H-5606 compatible with synthetic DOT4 brake fluid?

We have no documentation showing these two fluids are compatible. We recommend only using the fluid the brake manufacturer has called out to be used with their system.

Q: Is this product compatible with 1977 Piper hydraulic brake systems?

There is no application chart available. This product is 5606 which is commonly used in most general aviation aircraft.

Q: What is the shelf life of Phillips X/C MIL-PRF-5606H hydraulic fluid?

We do not have a set shelf life on our Aviation Oils. This is because there is simply no way for us to control how it is stored once it leaves our warehouse. If it is stored indoors under controlled conditions (i.e., not exposed to weather, direct sunlight, excessive heat or dust) then it can remain a high quality product for many years. A good guideline is: Once it is more than 5 years old, a sample of the product should be tested to verify quality. We have tested sealed containers much older than this and found them to be in great condition.

Please note that some militaries require retesting on their own schedule. We also encourage you to verify any FAA requirements with an FAA inspector (not an internet chat-room) and follow that person’s guidance.

Q: Can you attach the SDS non hazardous sheet on the product page?

We have added the SDS to the web page for review in the Documents section.
