The reliable and economic hydraulic fluid used on all types of aircraft
HYDRAUNYCOIL FH 51 is a petroleum-based hydraulic fluid with a viscosity of 14 cSt at 40°C. It contains anti-corrosion and anti-wear additives. HYDRAUNYCOIL FH 51 has an extremely wide operating temperature range (from -54°C to +135°C in air-tight circuits and -54°C to +90°C in open circuits) and a viscosity index exceeding 300. It is micro-filtered and supplied with a controlled level of contaminant.

Hydraulic fluid for flaps and slats transmission systems
General hydraulic systems of military aircraft, helicopters and missiles
Recoil systems of tanks and canons
HYDRAUNYCOIL FH 51 is the original NYCO hydraulic fluid used on all types of aircraft. It is a reliable and economic solution used as shock strut fluid for many commercial aircraft landing gears (Airbus, ATR, Bombardier, Fokker, Embraer, etc.).
HYDRAUNYCOIL FH 51 has been used for more than 50 years on Dassault Aviation Mirage fighters equipped with Messier-Hispano-Bugatti landing gears.
