# Oil specification

The behavior “In-service” of a hydraulic equipment heavily depends on the quality and characteristics of the hydraulic fluid selected. The choice of the specification and viscosity of the hydraulic fluid should be based of the conditions of use, taking into account several factors as follows:

- The range of environmental temperature.

- The range of oil viscosity defined for the equipment.

- The application (for example: range of pressures, sources of contamination of the hydraulic fluid, the type of pump).

- The ease of getting a proper replacement or equivalent hydraulic liquid.
