Heavy Duty Screw to Connect Couplings

Connect Under Pressure: Heavy duty screw-to-connect quick couplings are built to withstand the demanding requirements of applications where hydraulic lines are subjected to the stress of high-pressure impulses. The ability to connect and disconnect fluid lines while under pressure allows equipment operators to switch-out tool attachments without first having to spend time bleeding pressure off the system. Parker’s FET and 59 Series high pressure screw to connect hydraulic couplings have flush face valves that are designed for non-spill operation, virtually eliminating fluid loss at disconnection and featuring low air inclusion at connection. Air inclusion in a hydraulic system causes diminished performance and increased wear of system components. The non-spill valves guard against damaging pressure checking from trapped air in the lines.

Non-Spill Couplings

Flush face valving delivering dripless connections and disconnections: Parker’s non-spill couplings significantly reduces spillage upon disconnection. With a wide range of couplings solutions to fit versatile fluid applications, Parker’s non-spill couplings include the FEM Series, FET Series and 59 Series. All provide minimal fluid loss and air inclusion. The FEM Series satisfies the design and performance requirements set forth by the ISO 16028 International Standards for quick coupling interchangeability. Parker's FET Series is comparable with similar high-pressure thread-to-connect couplings by other manufacturers. Ideal for use in high impulse applications with multiple high-pressure hydraulic lines, the 59 Series ensures consistent connections and disconnections under residual pressure..

Fire Rescue Quick Couplings

Setting the Industry Standard for Interchangeable Couplings: In 2018, the National Fire Protection Association (NFPA) selected a Parker quick coupling design to adopt as the industry standard for manufacturers to follow for designing and building interchangeable couplings. A universally standard coupling compatible across all new and existing SCBA gear ensures firefighters will not have to remove their facepiece during an air supply malfunction or failure. Plus, fire departments and personnel can become thoroughly familiar with one standardized system and how it works. This ensures connectability of all buddy breather air couplings that may need to be connected or disconnected in the event of an emergency.
