Parker Stratoflex’s ground service equipment (GSE) quick disconnect (QD) couplings provide a proven solution for making the connection from the hydraulic ground service cart to the aircraft hydraulic system supporting routine ground maintenance. These GSE QDs are specifically designed as the interface from ground cart to aircraft for 3,000 psig hydraulic systems and are commonly used on both commercial and military programs. The flight side QD nipple half and cap are typically installed on the aircraft hydraulic system service panel or in other locations where appropriate to provide the access point for the hydraulic system servicing connection interface.
The GSE QDs use established engineering and design experience to provide this thread-together style connection with a visual and touch confirmation of proper coupling to improve both time and safety. The design incorporates a ratchet-tooth style latching mechanism to ensure that once the two coupling halves are threaded together and fully connected, they are positively locked in place. The ratchet teeth engage to prevent unintentional disconnection of the coupling halves; they provide a secondary locking feature for added safety and security. To disconnect, the outer actuating collar on the coupler half (ground side) is pulled back, releasing the ratchet teeth engagement and while being pulled back, rotated in the counterclockwise direction until fully unthreaded.
GSE couplings incorporate a self-sealing valve that permits fluid flow with minimum pressure loss and turbulence, plus a flush-faced design minimizes air inclusion or spillage during coupling or uncoupling. The design allows for simple one-handed operation to connect (thread-on) or disconnect (unthread) the coupling halves during ground service and maintenance of the hydraulic fluid system. As the coupling halves are threaded together, the fluid-flow path opens and when in the fully-open position (hand tight, ratchet teeth fully engaged), the GSE QD connection is complete.
The GSE QD consists of two halves, the nipple (441xx series) which is mounted on the aircraft and provides access to the aircraft hydraulic system. The coupler (440xx series) is the interface on the hydraulic ground service cart. The nipple QD half has provision for a latching cap to be installed (C44000 series) to ensure protection of the sealing surfaces during normal aircraft operation. The ground coupler QD half can be protected from foreign object damage, dropping and dragging handling damage in the sometimes harsh ground cart environments using the latching plug (P44000 series). Parker’s GSE QDs provide proven reliability for today’s standard interface for aircraft utilizing 3,000 psig hydraulic systems.
See the Parker Stratoflex product brochure (Catalog 106-GSE) for size and dimensional information.
Standard QD end fittings include:
• SAE MS33656, MS33657 male flared fitting
• SAE AS4395, AS4396 male flared fitting
• SAE AS33514, AS33515 male flareless fitting
The GSE quick disconnect series has been proven over years of service and a history of reliability both in the air on the ground. The baseline qualification for this product is built on the applicable requirements of industry standard SAE AS1709 specification.
For 4,000 and 5,000 psig hydraulic operating system pressures, Parker Stratoflex offers our robust Thread-Lok QD product adapted specifically for ground service applications. Thread-Lok applications are ideal for high vibration, shock, and impulse load environments. The mechanical advantage of connecting the coupling halves with a thread-together design, often provide the most robust performance in systems including engines, landing gear and brake systems.
Contact the Stratoflex Products Division with interface and performance requirements to determine if this product is the best choice for your installation and application.
