Castrol Brayco Micronic 881 Low Temperature Hydraulic Fluid, 1 Quart

Castrol Brayco® Micronic 881 is a fire resistant, synthetic hydrocarbon base, low temperature ISO viscosity Grade 7, red-colored hydraulic fluid for aircraft, missile, ordnance, and industrial use. It is specifically designed for low temperature applications where low temperature stability is particularly important. This product also provides controlled rubber swell for long seal life, low foaming properties, excellent anti-wear, corrosion protection, and oxidation stability. Operating temperature range -54ºC TO 135ºC (-65ºF TO 275ºF).

APPLICATIONS
Castrol Brayco Micronic 881 is designed as a low temperature fire resistant hydraulic fluid for aircraft and missile use but has use in many industrial applications as well.

TECHNICAL INFORMATION
Castrol Brayco® Micronic 881 is qualified to MIL-PRF-87257C.
