PRODUCT DESCRIPTION
AMSOIL Synthetic Water
Resistant Grease (GWR) 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.
