Polytac®EP (old)

Multipurpose Extreme-Pressure Polyurea Grease

Phillips 66®Polytac EP is a high-performance, multipurpose, extreme-pressure polyurea grease specially developed to provide long service life in automotive and industrial applications. It provides significant performance advantages over conventional soap-thickened greases in high-temperature, long-life and sealed-for-life applications.

Features & Benefits

• Excellent high-temperature performance

• Excellent shear stability

• Excellent wear protection

• High load-carrying capacity

• Excellent resistance to water washout

• Protects against rust and corrosion

• Excellent low-temperature pumpability

• NLGI GC-LB certified


• Automotive wheel bearings, chassis parts, constant-velocity (CV) joints and underhood applications, such as alternators, air conditioner compressor clutch bearings, water pumps and idler pulleys

• Sealed-for-life bearings

• High-speed antifriction bearings

• Agitator bearings in washing machines

• Equipment in steel mills and chemical plants exposed to chemical contaminants

• Industrial applications where a high-temperature, long-life, extreme-pressure grease is required
