Parker Stratoflex 598404-2 - Slide-Lok 1/8in Lanyard

With a standard end fitting, None seal package for hydraulic service, and refer to catalog tube size in the Parker Stratoflex 598xx series, the 598404-2 is a Slide-Lok lanyard-release quick-disconnect coupling with a remote pull-lanyard disconnect for limited-access installation points rated to refer to catalog psig. Qualified to SAE AS1709, it delivers the push-to-connect, self-sealing performance that defines the Slide-Lok series.

Key Features

• Remote lanyard-release mechanism enables deliberate disconnect from a remote location, ideal for confined-space or panel-obstructed plumbing
• Self-sealing valving on both halves, minimizes fluid spillage and air inclusion on disconnect
• Stainless steel construction for corrosion resistance and aircraft electrical bonding compatibility
• standard end fitting, compatible with standard aerospace plumbing interfaces
• None seal package, approved for hydraulic service
• Streamlined low-pressure-drop valve for refer to catalog size flow
• Operating pressure: refer to catalog psig at refer to catalog; series range vacuum to 5,000 psig
• Qualified to SAE AS1709, the baseline specification for aerospace quick-disconnect couplings
• Mating nipple: refer to catalog
• Accessories: protective dust caps, redundant seal pressure caps, thermal relief valves, keyed indexing, remote lanyard release

Applications

Parker Stratoflex Slide-Lok couplings serve on the F-15, F-16, F/A-18, F-22, C-17, Lockheed C-130, and Patriot missile launcher, as well as Formula One racing team hydraulic systems. The 598404-2 is ideal for cooling, fuel, hydraulic, and pneumatic ground servicing where single-hand operation, minimal fluid loss, and a compact envelope are required. For high-vibration engine, landing gear, or brake system applications, Parker Aerospace recommends evaluating the Thread-Lok series instead.
