Castrol Brayco™ 795 is a petroleum-based, low viscosity hydraulic fluid for aircraft and industrial use, made from a blend of highly refined basestocks. It is designed for aircraft clutch and brake devices where a low temperature fluid is required; its special additives assist in providing quiet operation of clutch and brake devices, including the “no back brake device”. Operating temperature range −54 to 135 °C (−65 to 275 °F).
