Quick Couplings

Parker quick couplings

We offer Parker’s line of hydraulic and pneumatic quick couplings. For diameters exceeding 1-inch, we provide Dixon hose couplings. Quick couplers are used when hoses or implements require connection and disconnection without the use of tools. A quick coupling assembly consists of two parts—the coupler body and the nipple. When ordering, list coupler bodies and nipples as separate items rather than as a combination. 

How to Select Quick Couplings

Answer the following questions to determine which quick coupler would be most ideal for your application.

  • What are the functional requirements of the coupling?
  • What is the maximum working pressure of the application?
  • Which seals and body material are compatible with the system’s fluid?
  • Is the application static or dynamic?
  • What size coupler is required?
  • What is the maximum pressure drop suitable for the application?
  • Does the application require the ability to connect and disconnect under pressure?
  • What is the media temperature and ambient temperature? 
  • What end configurations are required?
  • Is an industry interchange coupler required?
  • Is air inclusion and fluid loss a concern in the application?

Non-Standard Options

Many of Parker’s coupling products are available with unique, non-standard options well suited to very specific applications.

    Parker Snap-Tite hydraulic quick couplings

    Hydraulic Couplings | Snap-Tite Design

    Parker offers the H Series and PH Series Snap-tite design couplings for hydraulic applications. In the H Series couplings, the poppet valve enables single or double shut-off valving. PH version couplers and nipples are valved with a connect-under-pressure feature. These steel couplers and nipples allow connection with H Series valved couplers and nipples when there is a residual pressure on the PH coupler/nipple side. It is recommended that only one half of the connection (coupler or nipple) be PH version, not both. Applications include industrial hydraulic lines, water and coolant lines, and mobile equipment.

    Parker FEM series hydraulic quick coupling, non-spill

    Non-Spill Hydraulic Quick Couplings

    Non-spill couplings are designed to minimize spillage and air inclusion when connecting or disconnecting. Parker’s line of non-spill couplings includes Series FF/FC, FEM/FEC, FS, FH, and NS.

    FF Series couplings have a sleeve locking mechanism prevents accidental disconnection. FF Series couplings are widely used in the public utility market where hydraulic oil spillage can constitute a serious safety hazard, particularly in overhead bucket hoists that are used for maintenance of high-voltage power transmission lines. FC Series nipples provide a connect-under-pressure option for trapped pressures up to 3000 psi on the nipple side.

    FEM series couplings are designed to meet the stringent design and pressure requirements of ISO 16028 and are used where hydraulic spillage is a concern and global interchangeability with other manufacturers is important. The FEC Series nipple provides connect-under-pressure capability with up to 3000 PSI of trapped pressure in the nipple and are ideal for applications where residual pressure makes reconnect difficult. 

    FS Series stainless steel couplings have double shut-off flush mating valves that are suitable for sealing off media in chemical processing, chemical dispensing, food processing, and other corrosive applications.

    FH Series high pressure couplings are an innovative product combining the advantages of a flush-face design with a highly technical performance of a rated pressure of 10,000 PSI.

    NS Series Couplers and nipples are steel with nitrile seals. They utilize a PTFE back-up ring as additional support to the interface seal. Available in 1/2 inch through 1 inch
    sizes.
