CASTROL BRAYCO MICRONIC 776
High Response Hydraulic System Fluid
Brayco Micronic 776RP is a petroleum base, medium viscosity, light colored ISO Grade 22 hydraulic oil used in high performance hydraulic systems. It is a blend of selected, highly refined, high flash point base stocks with suitable additives to yield a product with unusually good anti-wear properties, low rubber swell, and excellent oxidation stability. It provides corrosion protection, dispersancy and is completely shear stable. Brayco® Micronic 776RP is specially processed to meet a guaranteed, low particulate contaminant level.

BRAYCO MICRONIC 776 Uses
Use Brayco® Micronic 776RP was developed for use in hydraulic systems that must respond with extreme accuracy. It was developed to replace aircraft hydraulic fluid in micro-hydraulic systems, computer programmed animation for robots, and other systems in which fire resistance, trouble-free operation, leak resistance, and fast precise responses are major requirements. In addition to its intended use, it is currently being used in computer and tape controlled hydraulic systems such as high precision automatic machine tools, data recovery systems, and in rail car control systems and brakes.
