Castrol Brayco™ Micronic 881 is a fire resistant, synthetic hydrocarbon base, ISO viscosity grade 7, red coloured low temperature hydraulic fluid for aircraft, missile, ordnance and industrial use. It is designed specifically for applications where low temperature stability is particularly important. It provides controlled rubber swell for long seal life, low foaming, excellent anti-wear, corrosion protection and oxidation stability. Service temperature is −54 to 135 °C. It meets MIL-PRF-87257F (2019 TDS in Odoo: MIL-PRF-87257C).
