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.
