Eaton AE99107E - Aeroquip 1800 Hose Half -4 (1/4")

The Eaton AE99107E is an Aeroquip 1800 Series Hose Attaching Half, Style I, AN size -4 (1/4"), for petroleum-based MIL-H-5606 and MIL-H-83282 hydraulic fluids service. Constructed from stainless steel for maximum corrosion resistance in flight-critical hydraulic circuits, this hose-end fitting attaches to the flexible hose side of the coupling pair. Rated to 3000 PSIG with Nitrile seals provide reliable compatibility with petroleum-based hydraulic media.

Flight-Critical Hydraulic Design

• Stainless steel body withstands aggressive hydraulic environments in aircraft wing and fuselage locations
• Style I hose-attaching half mates with the fixed bulkhead or port half in the aircraft system
• Self-sealing poppet valve eliminates fluid spillage on disconnection
• The compact 1/4-inch bore delivers precise, low-volume flow control for precise flow control in servo actuator circuits

The Aeroquip 1800 Series employs a low-profile ratchet lock mechanism — quarter-turn actuation locks the coupling under vibration and pressure cycling with minimal actuation force. Certified to MIL-C-25427A and AS1709, the AE99107E is qualified for aircraft flight controls, landing gear systems, and brake hydraulic circuits. For -4 (1/4") (narrow-bore), this coupling half is sized for servo actuator circuits, instrument hydraulic lines, and brake accumulator systems. Compatible with mil-h-5606 (red) and mil-h-83282 (fire-resistant) hydraulic fluids. Genuine Eaton Aeroquip part.
