Royco® 602 is a lubricating oil and coolant fluid for aircraft avionics systems and high-powered transmitters. It meets MIL-PRF-87252C.
Royco® 602 is a synthetic PAO-based coolant engineered for use in avionics and other sensitive electronic applications. Royco® 602 fluid is specifically engineered with robust hydrolytic stability and dielectric performance required in a wide range of modern technologies.
Royco® 602 oil does not react in the presence of water, leading to a much cleaner operating system and extending the lifespan of critical components.
