NYCO’s hydraulic fluids are:

  • Qualified by all air framers and OEMs
  • Available on all AMMs
  • Intermixable and miscible
  • Purchasable in a wide range of packaging
  • Obtainable worldwide, anytime, anywhere

Major international airlines choose NYCO’s FH 5 AW and FH 6 AW to be the sole shock strut fluid on their whole fleet (Airbus and Boeing…). The best solution for landing gears!

HYDRAUNYCOIL FH 51 (MIL-PRF-5606 H)

The original NYCO hydraulic fluid used on all types of aircraft. A reliable and economic solution.

Used as shock strut fluid for many commercial aircraft landing gears (Airbus ATR, Bombardier, Fokker, Embraer etc).

FH 51 has been used for more than 5 years on Dasault Aviation Mirrage III and IV equipped with Messier-Hispano-Bugatti landing gears.

HYDRAUNYCOIL FH 5 AW (BMS 3-32 A Type II)

All the qualities of FH 51 + a specific additive package to improve the fluid lubricity, an outstanding friction coefficient and extreme-pressuire efficient properties in operation.

As it retains fluidity down to -54°C, it is an efficient shock absorber during landing, even after prolonged high altitude cruise. Intended for use in landing gears of Boeing and Airbus aircraft.

HYDRAUNYCOIL FH 6 AW (BMS 3-32 A Type I)

FH 5 AW + great anti-corrosion properties for landing gears after overhaul or under storage. Used as a preservative or in operation.

The best multi purpose solution for Boeing and Airbus fleet.

HYDRAUNYCOIL FH 42 (MIL-PRF-87257 B)

The synthetic shock strut fluid for new generation aircraft.

Synthetic hydraulic fluid based on PAO and esters with a viscosity of 7cSt at 40°C. Designed to operate in the temperature range -54°C to +200°C for a long period of time without significant evaporation or change in viscosity.

Hydraunycoil FH 42:

  • Better and improved fire resistance
  • Outstanding fluidity at very low temperatures
  • Excellent resistance to shearing
  • Efficient prevention against component wear and seizure over a large temperature range

Applied in hydraulic systems previously operated with H-515 (MIL-PRF-5606) fluids without change of the elastomeric seals.
