Description
Castrol Brayco™ Micronic 756 is a petroleum base, low viscosity, red colored ISO Grade 15 hydraulic fluid for
aircraft, missile and ordnance use. It is a blend of highly refined, selected base stocks with suitable additives,
which yield a product with exceptionally good viscosity-temperature characteristics, good anti-wear properties, low
rubber swell, and excellent oxidation stability. The use of a polymeric viscosity index improver of low molecular
weight provides stability in comparison to typical hydraulic fluids.
Application
Brayco Micronic 756 is designed for use in aircraft, missile, and ordnance hydraulic systems where long term
stability and a low temperature fluid is required. Brayco Micronic 756 is filtered to meet rigid particle contaminant
requirements. It is intended for use in automatic pilots, shock absorbers, brakes, flap-control mechanisms, missile
hydraulic servo-controlled systems and other hydraulic systems using synthetic sealing materials. Fluids
compounded to meet this specification undergo certain changes with use. Further information relative to usable
life may be found in Fainman and Mackenzie, “The Characteristics and Performance of Specification MIL-H-5606
Hydraulic Fluid,” Lubrication Engineering 22234 (1966).
