7-50S hydraulic fluid-3
aviation oil
Description
Working fluid 7-50S-3 according to GOST 20734-75 – totally synthetic fluid contains special additives that improve antioxidant properties, as compared with mineral AMG-10 hydraulic oil.
Applications
It has a wide temperature operating range: up to + 175 ° C – long and up to + 200 ° C – briefly, unlike mineral oil AMG-10 (up to + 125 ° C and + 150 ° C, respectively) . Due fluid additive package has improved lubricity in the temperature range up to + 150 ° C. This feature improves the condition of the units and increases the service life of systems. Has an increased flash point, which greatly improves the fire safety of the liquid.
