AMSOIL Synthetic Water Resistant Grease

AMSOIL Synthetic Water Resistant Grease is the grease of choice in applications with frequent water exposure, such as the wheel bearings in boat trailers and tow vehicles.

A new additive technology enables GWR to resist water displacement and degredation. The grease offers superb cohesion and adhesion: it holds together and clings to metal parts when wet, even when wetted by a pressurized stream of water. In fact, testing shows GWR loses 47 precent less mass to water spray-off and 43 percent less mass to water washout than other greased do.

AMSOIL Synthetic Water Resistant Grease is compatable with most seal materials and other greases and is highly stable in storage.

Multi-Purpose NLGI No. 1.5 GC-LB Extreme Pressure Fortified

Resists water washout and degradation. Unparalleled protection for boat trailer wheel bearings and other components frequently exposed to water. Stays in place, lubricates and prevents rust.

PRODUCT DESCRIPTION

AMSOIL Synthetic Water Resistant Lithium Complex Grease is an extreme-pressure multi-purpose grease formulated specially for wet-duty performance. Its water washout and sprayoff resistance ideally suit it for use in the wheel bearings of vehicles and trailers frequently exposed to water, mud, snow or ice.

The grease is also excellent for use in plants, such as paper mills, in which machinery undergoes frequent or prolonged exposure to water.

Water Washout and Sprayoff Protection

AMSOIL Synthetic Water Resistant Lithium Complex Grease derives its superior wet-duty performance from its peerless cohesiveness and adhesiveness. Because the grease holds together when exposed to water and clings tenaciously to metal surfaces even when wet, AMSOIL Synthetic Water Resistant Lithium Complex Grease provides tough protection against water. Components remain protected during prolonged exposure to standing water or exposure to pressurized water.

Rust and Corrosion Protection

AMSOIL Synthetic Water Resistant Lithium Complex Grease protects metal surfaces from rust and corrosion, both of which may be hastened or worsened by frequent or prolonged water contact. It seals metal surfaces against rust and chemically fights corrosion.

High and Low Temperature Performance

AMSOIL Synthetic Water Resistant Lithium Complex Grease reduces friction effective, helping high-speed components run cooler than they can with other greases. It resists the damaging effects of high temperatures and oxidation so components stay deposit-free for optimal performance and long life.

AMSOIL Synthetic Water Resistant Lithium Complex Grease pumps easily at low temperatures for dependable cold temperature protection. Its low temperature pumpability makes the grease an excellent choice for use in automatic greasing systems.

In fact, AMSOIL Synthetic Water Resistant Lithium Complex Grease performs over such a broad temperature range, it may be used in place of separate high-temperature and low-temperature greases.

Load Carrying and Extreme Pressure Performance

AMSOIL Synthetic Water Resistant Lithium Complex Grease protects components from metal-to-metal contact even under heavy loads. Its extreme pressure additives form a shield against sustained or sudden extreme loads for dependable protection against wear.

Compatibility

AMSOIL Synthetic Water Resistant Lithium Complex Grease is compatible with most seal materials and most other greases.

Service and Shelf Life

AMSOIL Synthetic Water Resistant Lithium Complex Grease resists oxidation, high temperature degradation and additive depletion so effective, the grease may be used for longer service intervals than conventional greases may be used. AMSOIL Synthetic Water Resistant Lithium Complex Grease also resist oil separation and offers a long shelf life.

APPLICATION

AMSOIL Synthetic Water Resistant Lithium Complex 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. 1-1/2 GC or LB grease is recommended.

AMSOIL Synthetic Water Resistant Lithium Complex Grease's unique water resistant formulation makes it ideal for use in components or equipment with frequent or prolonged water exposure.
