PremiumExtreme-Pressure, Corrosion Preventive Calcium Sulfonate Grease

Phillips 66®Omniguard is a high-performance, multipurpose, extreme-pressure (EP), corrosion-preventive grease specially developed for use in industrial and automotive equipment operating in wet or corrosive environments. It is particularly recommended for equipment exposed to water contamination, saltwater corrosion and/or high temperatures.

Features & Benefits

• Excellent oxidation resistance and thermal stability at high temperatures

• Outstanding rust and corrosion protection, including resistance to saltwater corrosion

• Excellent extreme-pressure and antiwear properties

• Outstanding resistance to water washout

• Excellent shear stability

• High dropping point (>550°F)

• Light-colored, low staining

• NLGI GC-LB certified (Grade No. 2)


• Industrial and automotive equipment operating at high temperatures and exposed to water contamination, high humidity or corrosive environmental conditions

• Marine equipment, heavy mobile equipment and cables exposed to salt water

• Paper machine wet- and dry-end bearings and hot calender stacks
