Seal Oil Systems

Seal oil systems are used extensively in the offshore industry particularly on production machinery.

They are used on equipment where there are significant pressure differentials from the internal process and the atmosphere such as axial gas compressors. Seal oils are normally thin, have good thermal stability and are free from solid, anti-wear or EP additives. 

Viscosity is critical and OEM guidance is required, always consult your Castrol Technical Service Engineer.
