Eaton AE99119G - Aeroquip 1800 Hose Half -6 (3/8")

The Eaton AE99119G is an Aeroquip 1800 Series Hose Attaching Half, Style II, AN size -6 (3/8"), for Skydrol and phosphate ester hydraulic fluid systems. As a Style II half, it creates mid-hose detachable connections in Skydrol-service hydraulic hose assemblies — both mating halves are hose-end fittings. EPR seals and PTFE backup rings protect against phosphate ester degradation. Rated to 3000 PSIG across -65°F to +275°F (-54°C to +135°C).

Mid-Hose Skydrol Disconnect Design

• Style II configuration creates a mid-hose break point in phosphate ester hydraulic circuits
• Stainless steel body resists Skydrol exposure in airframe and equipment bay environments
• EPR seals maintain elasticity and low compression set in Skydrol 500B-4 and LD-4 service
• 3/8-inch bore provides practical flow capacity for secondary circuits supports flight control actuators on Skydrol aircraft

Certified to MIL-C-25427A and AS1709 for aircraft flight controls, landing gear systems, and brake hydraulic circuits. The low-profile ratchet lock mechanism — quarter-turn actuation locks the coupling under vibration and pressure cycling with minimal actuation force ensures the coupling remains locked under vibration and pressure without tools. Cross-reference fluid spec before installation — do not mix petroleum-grade and Skydrol-grade coupling halves. Sized for flight control actuators, brake systems, and utility hydraulic circuits at the -6 (3/8") flow rate.

Commercial Airline Hydraulic Applications

• Mid-hose break points in commercial airline Skydrol hydraulic circuits
• Hose routing disconnects for component access in phosphate ester hydraulic systems
• Airline maintenance facility hose assembly replacement procedures
• MRO shop hose assemblies for Skydrol system servicing (flight control actuators, brake systems, and utility hydraulic circuits)
