Castrol Brayco Micronic 756

VISCOSITY - ISO 14

Hydraulic Fluid, Petroleum Base

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.

APPLICATIONS

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 servocontrolled 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).
