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 viscositytemperature
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.
Uses :
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).
Specification :
Brayco Micronic 756 meets the requirements and is qualified under military specification MILPRF-5606H.
This fluid is identified by Military Symbol: OHA and NATO Code Number: H515.
