What is a key characteristic of petroleum base hydraulic fluid?

Petroleum base hydraulic fluids are commonly used in hydraulic systems due to their favorable properties. One of the key characteristics is that they are typically less flammable than other types of fluids, particularly in comparison to water-based or other synthetic fluids. The non-flammability is a significant advantage in reducing fire hazards, especially in industrial settings where hydraulic systems operate under high pressure and high temperatures.

Moreover, petroleum-based fluids have specific flash points that make them safer in certain applications. They are engineered to provide good lubrication, thermal stability, and resistance to wear, making them effective in hydraulic systems without the same degree of risk associated with more flammable fluids.

Understanding the properties of hydraulic fluids is crucial for ensuring the safe operation and longevity of hydraulic equipment. This focus on safety and operational effectiveness is why being non-flammable is highlighted as a characteristic feature of petroleum base hydraulic fluids.
