Description
    Parker Stratoflex’s single shut-off coupling (SSC) is designed with self-sealing valving to prevent fluid leakage when disconnected from the fluid system. The SSC provides one-side sealing of fluid when disconnected. Used in aircraft hydraulic systems and located at the interface of the engine-driven pump or similar equipment, the SSC is installed on the flexible hose assembly and threads on to an industry standard fitting at the pump, SAE AS4375, AS33514 or bulkhead fitting equivalents.

    Operation and use of the SSC is simple, positive and reliable. In the fully connected and torqued (installed) position, the SSC valving is open to flow and provides low pressure drop performance. To uncouple, the SSC outer collar is untorqued and unthreaded from the mating standard male fitting. As the SSC is unthreading, the internal valving seals and prevents excess loss of fluid from the SSC and flex hose side of the connection. The standard fitting side remains open, with no self-sealing valving on that side of the connection to retain fluid. Once fully disconnected, the pump or mating equipment and fitting are able to be removed and replaced as required.

    Parker Stratoflex SSC’s use proven engineering and design experience to provide a small size and light weight design with performance requirements to meet industry Standard SAE AS1896.

    Standard SSC end fittings include:
    • SSC male fitting (hose connection side): SAE AS4375, AS33514
    • SSC mates with equipment fitting (pump side): SAE AS4375, AS33514, AS4376, AS33515

    APPLICATIONS:
    The single shut-off couplings are used on a variety of aerospace and related applications where proven performance and sealing on one-side only when disconnected is a key requirement along with small size, light weight, and high reliability are important for systems in service today. Programs using the Parker Aerospace SSC include military aircraft hydraulic systems for C-5, C-17, P-8, 767-2C tanker, A400M, and commercial hydraulic systems for 737NG, 747-400, 757, 767, 777, 787, A350 and the Dash-8-400.

    FEATURES AND ATTRIBUTES:
    • Provides ease of system maintenance in removing engine-driven hydraulic pump or similar equipment while sealing fluid on the flex hose side and preventing excessive spillage or fluid contamination
    • Engineered, tested, and qualified to provide long-term reliable service in harsh engine environments
    • Thread to connect with standard fitting to open self-sealing valve and fluid flow
