ROYCO 363-GL LOW TEMP. LUBRICANT (MIL-PRF-7870D)

ROYCO 363-GL Low Temp. Lubricant (MIL-PRF-7870D) is a refined mineral-based oil engineered to preserve and lubricate critical mechanisms exposed to sub-zero conditions. Its balanced additive system delivers dependable film strength, corrosion resistance, and oxidative stability on metals commonly found in aircraft and support systems, including steel and aluminum alloys. The formulation maintains fluidity at low temperatures to prevent start-up wear, sticking, or component seizure during service or storage in arctic or high-altitude environments, making it suitable for hydraulic accessories, actuators, linkages, and general mechanical assemblies in military and civilian aerospace operations.
