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.
