MIL-PRF-46170E

MIL - PRF – 46170E, PERFORMANCE SPECIFICATION: HYDRAULIC FLUID, RUST INHIBITED, FIRE RESISTANT, SYNTHETIC HYDROCARBON BASE (NATO Code H-544)

This specification covers the requirements for one type of synthetic hydrocarbon base hydraulic fluid intended for use in the -40C to 200C temperature range in recoil mechanisms, military ground vehicles, and equipment hydraulic systems. The hydraulic fluid operates at a wide range of temperatures and is thermally stable, rust/corrosion inhibited, fire resistant, and may be used as a preservative medium for hydraulic systems and components. The combination of all of these fluid properties is not found in commercial hydraulic fluids. It will not be used for aircraft systems, aircraft ground support equipment, or the preservation of aircraft components.

This fluid is adopted for military use by NATO countries.

Type I - Undyed and Identified by Military Symbol FRH and NATO Code H-544.
