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.
