Parker Quick Coupling Division Construction & Forestry

Large and small construction and forestry equipment often use a variety of tool attachments allowing them to be versatile for several activities and efficiently perform the work. Some of these attachments require multiple connections to the hydraulic lines, depending on the equipment and its function. At the job site, equipment tool attachments might be changed out several times in the process it takes to complete the project. Quick couplers for excavators and other heavy-duty equipment save time and improve efficiency by allowing operators to quickly and easily disconnect and reconnect hydraulic lines when switching out the tools or attachments.

Screw-to-connect, high pressure couplings are built to withstand the demanding requirements of applications where hydraulic lines are subjected to the stress of high pressure impulses and vibration. Parker's FET Series and 59 Series allow the hydraulic lines between the equipment and the tool attachments to be quickly disconnected and reconnected without extensive downtime. These heavy duty, high pressure screw to connect couplings are rated for pressures up to 6000 psi and can be connected and disconnected while hydraulic lines are under residual pressures. Parker FET and 59 Series also have flush face valves that are designed for non-spill operation, virtually eliminating fluid loss at disconnection and featuring low air inclusion at connection.
