Aircraft contain complex systems that make up 40–60% of their total weight. Key components include electrical, pneumatic, air conditioning, and fuel systems. Among these, hydraulic systems are essential, as they power many critical functions.


Aircraft—including commercial, military, and helicopters—require specialized hydraulic fluids, unlike those used in industrial or mobile equipment. Aviation hydraulic fluids must withstand extreme heat and be non-flammable.

Aeronautic hydraulic couplings must endure high pressure, heat, vibrations, and torsion. EHHYDRAULIC’s hydraulic couplers and valves meet these demands with certified materials and gaskets.

EHHYDRAULICHYDRAULIC provides hydraulic quick couplers for tractors, forestry machinery, mini-excavators, and skid steers, enabling fast, leak-free attachment changes. Farming demands both environmental protection and rugged performance—EHHYDRAULICHYDRAULIC’s couplers, multi-coupling plates and valves deliver quick, efficient switching while preventing leaks and minimizing downtime.
