Eaton AE99148E - Aeroquip 1801 Hose Half -4 (1/4")

The Eaton AE99148E is an Aeroquip 1801 Series Hose Attaching Half, Style II, AN size -4 (1/4"), for Skydrol and phosphate ester hydraulic fluid ground service. A Style II half creates an in-line mid-hose quick-disconnect in a flexible Skydrol ground service hose assembly — both mating halves are hose-end type. Lightweight aluminum construction with EPR seals and PTFE backup rings delivers Skydrol chemical resistance at the 1000 PSIG ground service rating.

Skydrol Ground Service Hose Mid-Point Connection

• Style II enables in-line break points within Skydrol ground service hose runs
• EPR seals and PTFE rings on both mating halves ensure consistent Skydrol compatibility
• Aluminum construction minimizes ground service hose assembly weight
• Compact 1/4-inch bore delivers precise, low-volume flow control for Skydrol ground service servo actuator circuits

Certified to MIL-C-25427A and AS1709 for aircraft hydraulic ground service and fluid transfer operations. The low-profile ratchet lock mechanism — designed for reliable hand-operated disconnection under ground service conditions while maintaining a positive seal during pressurized operation provides reliable coupling security in ramp and hangar environments. The 1801 Skydrol ground service half is lighter and more economical than the flight-rated 1800 stainless Skydrol variant — appropriate for hose assemblies operating at ground service fluid transfer pressures. Always pair with other Skydrol-rated coupling halves.
