Coupling Grease (old)

High-Performance, Extreme-Pressure Lithium Grease
Phillips 66®Coupling Grease is a high-performance, polymer-containing lithium grease developed for use in grease-lubricated flexible couplings, such as those commonly found in mining equipment, power plants, manufacturing plants and chemical plants. It has exceptional resistance to oil separation when subjected to the high centrifugal forces typically encountered with medium and high-speed gear, metallic grid and chain couplings.

Features & Benefits

• Outstanding resistance to oil separation

• Excellent oxidation resistance and thermal stability

• High load-carry capacity

• Protects against rust and corrosion

• Minimizes friction and wear to help extended coupling life


• Gear, metallic grid and flexible-chain couplings

• Couplings commonly used in mining and gas field equipment

• Couplings and universal joints operating under high centrifugal forces

• Couplings used between electric motors and gearboxes in industrial and chemical plants
