The importance of analysis

Eastman offers a sample analysis program to our customers. This service helps ensure your fluids remain within in-service limits, allowing you to identify potential issues early on and avoid potentially costly issues later.

During flight, hydraulic fluid can be influenced by environmental factors that may alter its properties, such as heat, moisture and cleanliness. We will assess your fluid’s viability following exposure to these conditions to support your operational needs.

These steps are general guidelines for obtaining a proper sample while ensuring the safety and quality of the results:

  • Pressurize and operate the hydraulic system for 10 to 15 minutes.
  • Wipe off the sampling port with a lint-free cloth.
  • Allow about 250 mL (1 pint) of fluid to drain to purge any settled particles from the sampling port.
  • Fill the bottle and cap immediately.
  • Close the drain valve.
  • Fill out the sample label.
  • Service system reservoirs to replace the fluid that was removed.

Fluid color specifications


Phosphate ester-based aviation hydraulic fluids are purple when new but may change color during service. Color is not a reliable indicator of quality. There is no in-service specification for fluid color. Rather, fluid should be free of cloudiness or suspended solids.
