Description
Castrol Alpha™ TT 1200 & 3200 are high quality, mineral oil based extreme pressure industrial gear oils with
high viscosity.
Alpha TT 1200 & 3200 contain a boosted sulphur-phosphorous extreme pressure (EP) additive, oxidation and
corrosion inhibitors, and possess demulsification and anti-foam properties.
Application
Alpha TT 1200 & 3200 are recommended for heavy duty industrial gearbox applications such as dragline gear
cases.
Alpha TT 1200 meets the requirements of Bucyrus specification RGL for Regular Type Gear Lubricant, along
with DIN 51517 Part 3 (CLP).
Advantages
 High viscosity and EP package for wear protection under heavy loads
 Corrosion inhibitors for maximizing equipment life
 Antioxidants maximize lubricant service life
