NYCO HYDRAUNYCOIL FH 4725 is a synthetic ester based hydraulic fluid  with a viscosity of 28 cSt at 40°C, a viscosity ind ex of 250 and a  flash point exceeding 200°C. 

NYCO HYDRAUNYCOIL FH 4725 can be used over an extremely wide  temperature range, from - 35°C to + 200°C in closed circuits. It is  formulated to provide adequate lubrication at high temperature  without corroding copper alloys and electrical wires.

NYCO HYDRAUNYCOIL FH 4725是一款有較高的粘度指數(shù)的航空液壓油，在密閉的工作系統(tǒng)中耐溫范圍- 35°C to + 200°C。

NYCO HYDRAUNYCOIL FH 4725 is a hydraulic and compensation fluid for  downhole tools used to measure the characteristics of formation  during well drilling, as well as the quality of the oil/gas/water mix  extracted from the well. It is also used to power wire-line tractors. It  is best suited for HT/HP wells (170-200°C / 700-150 0 bars).  HYDRAUNYCOIL FH 4725 is not corrosive at high temperature to the various alloys used in such  equipment, of which copper, and does not affect nitrile and Viton seals / gaskets.as/water mix  extracted from the well.
