Product Code: GWR
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.
