Castrol ALPHASYN EP 320
Synthetic Gear Oil
Product Description
Alphasyn EP 320 is a high-quality synthetic lubricant which has been formulated for use in all types of enclosed gears including heavy loaded / shock-loaded gears and bearings where EP properties are required. It is suitable for use in gearboxes where micro pitting resistance is required and for a wide range of applications in extreme environments.
Alphasyn EP 320 is based on polyalpha-olefin (PAO) fluids and Sulphur / phosphorus extreme pressure (EP) additive technology providing outstanding thermal stability and high load carrying capacity.
The use of a PAO base stock provides inherently high Viscosity Index (VI) and low pour points making this product suitable for use over a wide temperature range.
