HYDRAUNYCOIL FH 51PETROLEUM HYDRAULIC FLUIDNATO CODE H-515 – DCSEA 415/A – MIL-PRF-5606 H DEF STAN 91-48 Iss.2 – OM-15DESCRIPTIONHYDRAUNYCOIL FH 51 is a petroleum-based hydraulic fluid witha viscosity of 14 cSt at 40°C. It contains anti-corrosion and anti-wear additives.HYDRAUNYCOIL FH 51 has an extremely wide operatingtemperature range (from - 54°C to + 135°C in air-tight circuits and -54°C to + 90°C in open circuits) and a viscosity index exceeding300. It is micro-filtered and is supplied with a controlled level ofcontaminant.APPLICATIONHYDRAUNYCOIL FH 51 is used in hydraulic systems of military aircraft (jet fighters, transport aircraft,helicopters) or missiles, as well as general purpose hydraulic fluid for ground equipment (tanks, artillery…).It is also recommended as shock strut fluid for many commercial aircraft landing gears (Airbus, ATR,Bombardier, Fokker, Embraer, etc.).
