Castrol Alphasyn EP 680
The Castrol Alphasyn™ EP gear oil range comprises high quality synthetic lubricants based on poly-alphaolefin (PAO) fluids with sulphur/phosphorus Extreme Pressure (EP) additive technology, providing good thermal stability and high load carrying capacity. Formulated for all types of enclosed gears including heavy and shock-loaded gears and bearings, Alphasyn EP suits gear boxes requiring micro-pitting resistance and extreme environments such as mining and quarrying, marine applications, and paper production. The PAO base stock provides an inherently high Viscosity Index and low pour points for use across a wide temperature range, and the range is fully compatible with nitrile, silicone, and fluoropolymer seal materials.
