PRODUCT DESCRIPTION
AMSOIL Synthetic Water Resistant
Grease is an extreme-pressure, multipurpose grease formulated specially for
wet-duty performance. Its water washout and sprayoff resistance are ideal
for wheel bearings of vehicles and trailers frequently exposed to water,
mud, snow or ice. It 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
Grease derives its superior wet-duty performance from its peerless
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 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 Grease
effectively reduces friction, helping high-speed components run cooler. 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 Grease
may be used in place of separate high-temperature and lowtemperature
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.
Service and Shelf Life
AMSOIL Synthetic Water Resistant
Grease resists oxidation, high temperature degradation and additive
depletion so effectively, it may be used for longer service intervals than
conventional greases. AMSOIL Synthetic Water Resistant Grease also resists
oil separation and offers a long shelf life.
APPLICATION
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. AMSOIL Synthetic Water Resistant Grease is
compatible with most seal materials and most other greases.
