Pneumatic Quick Disconnects | Parker

    Quick couplers | Parker  Pneumatic QC Selection


    Back to Product Overview
    Pneumatic quick couplers (also referred to as air couplers, or pneumatic quick disconnects), are primarily used for pneumatic applications, connecting air tools, hoses, or other implements to compressed air supplies. They are also used with other gases, and (with the exception of the E-z-mate Series) can be used with low pressure fluids.

    The coupler half contains a shut-off valve that is automatically opened when a mating nipple is inserted and automatically closes when the nipple is removed.

    Parker pneumatic couplings come in three basic designs: general purpose/manual connect, general purpose/push-to-connect, and special purpose.

    The standard seal material for all Parker single shut-off couplers is Nitrile. Ethylene Propylene, Fluorocarbon, and Neoprene seals are available as options. Please consult the comprehensive Fluid Compatibility Chart for more information on seal and body material selection – or contact us for further assistance in selecting the appropriate seal material.

    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

    If several different series of couplings are being used in your plant or shop, consider using Industrial Interchange Nipples. Industrial Interchange Nipples work with the following couplers: Parker 20 Series, Parker HF Series, Parker 30 Series, Parker Universal Couplers, and Parker E-z-mate Series.

    Parker Industrial Interchange nipples are also interchangeable with similar nipples manufactured by other quick disconnect manufacturers conforming to A-A-59439 (formerly known as MIL-C-4109F), ANSI/(NFPA) T3.20.14-1990, or ISO6150-B requirements.
