Castrol Alpha? SP S gear oils are a range of high quality solvent refined mineral oils, fortified with sulphur-phosphorous
compounds to impart anti-wear and extreme pressure properties. Corrosion protection additives (VCI inhibitor) are also
added to give added corrosion protection on storage after use.
Application
Castrol Alpha SP S oils are recommended for the lubrication of industrial gearboxes with forced circulation or splash and
oil bath lubrication. Especially useful for storage and/or transportaion of gears. Can be used if equipment needs to be
"mothballed".
Advantages
Excellent thermal stability and oxidation resistance.
Long oil life.
Good water resistance and demulsification characteristics.
Rust and copper corrosion protection of metal surfaces.
Upto 24 months corrosion protection in closed transmissions
