Being a highly refined mineral oil based lubricant ROYCO 363 is formulated with modern additives to provide rust inhibition, oxidation and corrosion protection, good resistance to evaporation, and low temperature fluidity.

ROYCO 363 has limited use at high temperatures - unless provisions are made for frequent relubrication.

Meeting all the requirements ROYCO 363 is qualified to MILSPEC: MIL-PRF-7870C.

ROYCO 363 is recommended for the general-purpose lubrication of instrument and airframe components including bearings, actuators, hinges and latches on both military and civilian aircraft. It is suitable for use over the temperature range from -65°F to 250°F.
