Castrol Coral 2 Stern Tube Oil

Coral 2 stern tube oil is designed to readily emulsify with seawaterthus providing certain advantages over oils selected for demulsibilityin a wet environment.Firstly, oil/water emulsions provide a higher viscosity fluid thanneat oils thus minimising oil loss or water ingress.
Secondly, by sustaining an oil/water emulsion, corrosion from separated seawater, which can occur in a statically loaded sterntube bearing, is avoided.

APPLICATIONS
This grade has given satisfactory service in stern tubes employing awide variety of seals including Cedervall, Chuetsu-Waukesha, andSimplex Compact Seals.
Coral 2 has other applications in the marine environment, includingthe use in fin stabilisers and propeller hubs.

FEATURES/BENEFITS
Blended from selected mineral oils compounded with a natural emulsifier, this lubricant gives a stable high viscosity emulsion and goodrust protection.

APPROVALS STATUS
