AMSOIL Synthetic Water
Resistant Grease is an extreme-pressure grease
formulated specially for wet-duty performance.
Composed of premium-quality synthetic base oils
and calcium sulfonate complex thickeners, Water
Resistant Grease provides exceptional film
strength, shear resistance, adhesion properties
and mechanical stability. Its water washout and
sprayoff resistance are outstanding for
applications frequently exposed to water, mud,
snow or ice, including ATVs, UTVs, snowmobiles
and boat trailers.
Water Washout and Sprayoff
Protection
AMSOIL Synthetic Water Resistant Grease gains
its wet-duty performance from its superior
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
or pressurized water.
Corrosion Protection
AMSOIL Synthetic Water Resistant Grease protects
metal surfaces from corrosion, which may be
worsened by frequent or prolonged water contact.
It seals metal surfaces and chemically fights
corrosion.
Load-Carrying and
Extreme-Pressure Performance
AMSOIL Synthetic Water Resistant Grease protects
components from metal-to-metal contact even
under heavy loads. Its extreme-pressure
additives protect against sustained or sudden
extreme loads for dependable protection against
wear.
Application
Recommendation
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.
Compatibility
AMSOIL Synthetic Water-Resistant Grease is
compatible with many other types of greases.
However, it is recommended that when changing
greases, the equipment be cleaned of the old
grease when possible or flushed with a liberal
amount of Water-Resistant Grease while the
mechanism is in operation. Closely monitor the
system for any inconsistencies. Grease
compatibility questions should be referred to
your AMSOIL representative or AMSOIL INC.
APPLICATION
MAINTENANCE
Maintaining a clean work environment is
important when equipment greasing is performed.
Wipe grease fittings clean prior to injecting
grease to prevent contaminant ingestion.
Maintain bearing housings one-third to one-half
full of grease. Do not over-grease, as excessive
heat buildup can result. Supplement standard
grease maintenance by periodically cleaning and
packing housings with fresh grease on an
established maintenance schedule.
