Seals Manager Interview Questions and Answers

Hydraulic 68 viscosity at 40 degree temperature is a measure of the oil's resistance to flow.

• Viscosity refers to the thickness or resistance to flow of a fluid.

• Hydraulic 68 is a specific type of hydraulic oil with a viscosity grade of 68.

• At 40 degrees temperature, the hydraulic 68 oil will have a certain viscosity value.

• The viscosity value determines how well the oil can lubricate and protect hydraulic seals.

Oil viscosity refers to the thickness or resistance to flow of an oil.

• Viscosity is measured in units of centistokes (cSt) or Saybolt Universal Seconds (SUS).

• Higher viscosity oils are thicker and flow more slowly, while lower viscosity oils are thinner and flow more easily.

• Viscosity is influenced by factors such as temperature, pressure, and the type of oil.

• Different applications require different viscosity levels, such as engine oils, hydraulic fluids, or gear oils.
