preservative fluid for aircraft and ordnance use. It is a blend of selected petroleum oils with additives which
provide exceptionally good viscosity-temperature characteristics, good anti-wear properties, controlled rubber
swell, good shear stability and excellent oxidation resistance. Brayco Micronic 783 is an excellent corrosion
