Adhesive, Multipurpose Extreme-Pressure Lithium Grease

Phillips 66®RedTac is an adhesive, multipurpose, extreme-pressure lithium grease developed for use in a wide variety of automotive and industrial applications. It contains a polymer and a tackiness additive that provides improved retention, reduced leakage and outstanding resistance to water washout.

Features & Benefits

• Good high-temperature performance

• Adhesive; stays put

• Excellent resistance to water washout

• High load-carrying capacity

• Excellent wear protection

• Protects against rust and corrosion

• Good low-temperature pumpability


• Automotive chassis parts such as steering knuckles, ball joints, U-joints and tie-rod ends

• Wheel bearings on passenger cars and heavy equipment equipped with drum brakes

• Moderately loaded plain and rolling-element bearings in industrial equipment

• Enclosed industrial gear drives that require a semi-fluid, heavy base oil, extreme-pressure grease (NLGI Grade No. 0)

• Agricultural and construction equipment where an adhesive, water-resistant, extreme-pressure lithium grease is required
