# CASTROL Alpha SP 680

CASTROL Alpha SP 680 is a high-quality EP gear oil.

#### Description

Castrol Alpha™ SP 680 gear oil is based upon highly refined mineral oil, enhanced with an extreme pressure additive technology providing good thermal stability and high load carrying capacity. The extreme pressure additive system not only provides high load carrying capacity, but was designed to provide microscopic wear protection. Microscopic wear protection, also known as micropitting protection, is critical in preventing destructive wear at the micro level therefore extending gear life and meeting the evolving demands of smaller and higher output gear boxes.

#### Application

Castrol Alpha SP 680 is recommended for the lubrication of industrial gear boxes using forced circulation or splash and oil bath lubrication. It may be used for the lubrication of spur and helical gears and in some lightly loaded worm type gear applications. It has very good viscosity characteristics to ensure starting torques are not excessively high in cold operating conditions. The additives are compatible with the ferrous and non-ferrous metals used in industrial gear units. Castrol Alpha SP 680 is compatible with the most common types of seal materials.
