Product Applications
AMSOIL Synthetic Water Resistant Grease meets the highest performance standards set by the National Lubrication Grease Institute (NLGI), GC for wheel bearing applications and LB for chassis applications. It may be used in automotive wheel bearings, chassis or other applications for which an NLGI No. 2 GC or LB grease is recommended. Its unique water-resistant formulation makes it ideal for use in components or equipment with frequent or prolonged water exposure.

Product Description
AMSOIL Synthetic Water Resistant Grease is an extreme-pressure grease formulated specially for wet-duty performance. Composed of premium-quality synthetic base oils and calcium sulfonate complex thickeners, Water Resistant Grease provides exceptional film strength, shear resistance, adhesion properties and mechanical stability. Its water washout and sprayoff resistance are outstanding for applications frequently exposed to water, mud, snow or ice, including ATVs, UTVs, snowmobiles and boat trailers.

Water Washout and Sprayoff Protection
AMSOIL Synthetic Water Resistant Grease gains its wet-duty performance from its superior cohesiveness and adhesiveness. It holds together when exposed to water and clings tenaciously to metal surfaces when wet. Components remain protected during prolonged exposure to standing or pressurized water.

Corrosion Protection
AMSOIL Synthetic Water Resistant Grease protects metal surfaces from corrosion, which may be worsened by frequent or prolonged water contact. It seals metal surfaces and chemically fights corrosion.

Load-Carrying and Extreme-Pressure Performance
AMSOIL Synthetic Water Resistant Grease protects components from metal-to-metal contact even under heavy loads. Its extreme-pressure additives protect against sustained or sudden extreme loads for dependable protection against wear.

Compatibility
AMSOIL Synthetic Water-Resistant Grease is compatible with many other types of greases. However, it is recommended that when changing greases, the equipment be cleaned of the old grease when possible or flushed with a liberal amount of Water-Resistant Grease while the mechanism is in operation. Closely monitor the system for any inconsistencies. Grease compatibility questions should be referred to your AMSOIL representative or AMSOIL INC.

AMSOIL Product Availability
AMSOIL Synthetic Water Resistant Grease is available in 3-oz. cartridges, 14-oz. cartridges, 35-lb. lugs and 120-lb. kegs.
