Pressure-Free Return Circuit

This connector provides pressure-free oil return.

Examples of implements which cannot withstand high pressure in the return line:

• Hydraulic motors which have a pressurized oil return. Failure of the motor housing or shaft seals may result if the return line is pressurized.
• Remote hydraulic valves located on the implement may allow unexpected movement of cylinders if the return port is pressurized.

When the pressure-free return circuit is not in use, use the protective dust cap.
