Eaton AE99115H - Aeroquip 1800 Hose Half -8 (1/2")

The Eaton AE99115H is an Aeroquip 1800 Series Hose Attaching Half in Style II configuration, AN size -8 (1/2"), for petroleum-based MIL-H-5606 and MIL-H-83282 hydraulic fluids service. Style II enables hose-to-hose quick-disconnect configurations — both mating halves are hose-end fittings, creating a detachable connection point in the middle of a flexible hydraulic hose assembly. Rated to 3000 PSIG with stainless steel construction and Nitrile seals provide reliable compatibility with petroleum-based hydraulic media.

Style II Hose-to-Hose Configuration Advantages

• Both coupling halves are hose-end attachments — no fixed bulkhead or panel fitting required
• Enables mid-hose disconnection for component removal or circuit isolation
• Particularly useful in cramped aircraft spaces where a panel-mounted bulkhead half is impractical
• The 1/2-inch bore handles medium system flow rates for primary aircraft hydraulics for routing through main hydraulic circuits applications

Stainless steel construction gives the AE99115H superior resistance to corrosion and hydraulic fluid degradation throughout -65°F to +275°F (-54°C to +135°C). The low-profile ratchet lock mechanism — quarter-turn actuation locks the coupling under vibration and pressure cycling with minimal actuation force provides secure locking without tools. Certified to MIL-C-25427A and AS1709. Compatible with mil-h-5606 (red) and mil-h-83282 (fire-resistant) hydraulic fluids.

Hose Assembly and System Integration Uses

• Mid-hose quick-disconnect points in aircraft hydraulic hose assemblies
• Equipment removal break points in hydraulically powered systems
• Flexible hydraulic hose routing through aircraft structures
• Test and maintenance circuit isolation for main hydraulic circuits, landing gear systems, and primary flight control actuators
