Contamination control is a crucial for hydraulic systems to survive and to sustain their reliability and performance. Hydraulic fluids are inevitably contaminated by various sources. Hydraulic fluid contamination is not limited to just the particulate contaminants as many people may think. Hydraulic fluid contamination can be broadly defined as any internal or external reason that can change the properties or performance.

Therefore, this textbook focuses on hydraulic fluids and contamination control. The text book discusses thoroughly the different types of hydraulic fluids, their properties and standard methods of testing. The textbook also covers all types of contamination, their sources, effects, and best practices to avoid and control them.

With 30+ years of experience in teaching fluid power for industry professionals, the author had effectively applied his solid understanding to the subject and his post-doctoral level of academic education in developing this book.
