Hydraulic Quick Disconnects | Parker

    parker-hydraulic-qc Skip to Hydraulic QC Selection

    Parker hydraulic couplings are available in a wide variety of designs, each tailored to a particular application. Each Parker hydraulic coupler generally falls into one of two groups: Double Shut-Off coupling or Straight-Thru coupling.

    Parker Hydraulic Double Shut-Off couplings

    Parker Hydraulic Double Shut-Off couplings are used extensively when it is important to minimize fluid loss upon disconnection. Both halves of the coupler, the body and the nipple, contain shut-off valves. These valves open automatically when the body and nipple are connected, and close automatically when the two halves are disconnected, keeping fluid loss to a minimum.

    Parker Hydraulic Straight-Thru couplings

    Parker Hydraulic Straight-Thru couplings have no valves in either half and are ideal for maximum flow application. Their smooth, open bore offers the lowest pressure drop of any quick disconnect coupling, and allows them to be thoroughly cleaned. Since there are no valves in either half, fluid flow should be shut off before the coupling is disconnected.

    NEW! 6000 psi Non Spill QC

    Parker Introduces FET Series Couplings.

    Parker FET Series Non Spill QC

    • Working pressure up to 6000 psi
    • Connect under residual pressure up to 5000 psi
    • Disconnect under residual pressure up to 2500 psi
    • Interchanges with Stucchi VEP and similar European thread-to-connect couplings

    QC Selection Tips

    When ordering quick couplers, consider the following:

    • Functional requirements of the coupling
    • Maximum working pressure of the application
    • Coupler seal & body material compatibility with the system’s fluid
    • Is the application static or dynamic?
    • Size of coupler & hose
    • Maximum allowable pressure drop
    • Requirement to connect & disconnect under pressure
    • Media temperature
    • Ambient temperature
    • End configuration requirements
    • Need for industrial interchange QC
    • Effects of air inclusion & fluid loss

    Hydraulic QC Selection

    • Double Shut-Off QCs
    • Straight-Through QCs
    • General Purpose QCs
    • Non-SpillQCs
    • Connect Under PressureQCs
    • High Pressure QCs
    • High Flow QCs
    • Mold Coolant Line QCs
    • Miniature QCs (DM Series)

    Working Pressure

    Working pressure of Parker hydraulic couplings range from 30 to 15,000 PSI. Pressure rating of Parker hydraulic quick couplings are defined by ISO 5598, as “the qualified operating pressures which are recommended for a component or a system by the manufacturer.” Parker QC “Rated Pressures” have been established on the basis of laboratory tests which include, but are not limited to, static burst tests and multiple cycle impulse tests. System characteristics such as high cycling rates and high amplitude shocks either hydraulic or mechanical, can reduce the functioning life of a coupling, even if the system’s nominal pressure falls within the rated pressure range of the coupling.
