ROYCO® 717 Power Transmission Fluid

Old or low reserves of transmission fluid can spell big trouble in the skies. That's why SkyGeek carries top-rated ROYCO® 717 Power Transmission Fluid. The pale, straw - colored hydraulic fluid is blended with highly refined mineral base oils and modern additive technology to provide protection against rust, wear and demulsibility. It lubricates all of the individual components of your aircraft's transmission while simultaneously protecting it against oxidation and corrosion. The fluid has improved viscosity-temperature characteristics as well as several other enhancements to allow it to outperform the competition.

ROYCO® 717 is recommended for use in applications requiring a constant source of fluid power to hydraulic components, such as the transmission system of your aircraft. The fluid is suitable for use in hydraulic systems involving mechanical or fibrous type filters or centrifugal purification. It is noncorrosive to bearings and hydraulic systems and does not cause clogging of oil screens or valves. The fluid remains homogeneous over the temperature range of -34°C to 4°C.
