Mil-H-5606 Hydraulic Fluids are antiwear hydraulic fluids formulated to meet the intense demands of aerospace and industrial applications - these oils are mineral oil-based, high viscosity index, and may be used in a variety of applications including industrial and mobile applications.
Mil-H-5606 Hydraulic Fluids are known as aviation oils (though other uses and applications are common). These lubricants have outstanding low-temperature characteristics for use in a wide temperature range and have other increased performance characteristics in addition to resistance to rust and sludge formation. Mil-H-5606 Hydraulic Fluids provide optimal wear-protection for hydraulic system components and work to protect hydraulic system components against rust. These oils are also resistant to excessive foam buildup that can contribute to poor hydraulic system response.
The midpoint kinematic viscosity of this oil (derived from a range of kinematic viscosities) is 15 mm2/s, or centistokes (cSt). This number represents how well these oils resist flow.
