Synthetic Water Resistant Grease
Superior Lubrication and Protection in Automotive and Industrial Applications
Resists water washout and degradation. Unparalleled protection for boat trailer wheel bearings and other components frequently exposed to water.
Stays in place, lubricates and protects against rust.
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
The superior wet-duty performance of AMSOIL Synthetic Water-Resistant Grease can
be credited to its outstanding cohesive and adhesive properties. It holds together
when exposed to water and clings tenaciously to metal surfaces when wet, protecting
components during prolonged exposure to standing or pressurized water.
Frequent or prolonged water contact can increase corrosion, resulting in damage to
metal surfaces and compromised components. Water-Resistant Grease seals metal
surfaces and chemically fights corrosion, making it an ideal solution for applications
with extensive exposure to water, mud, snow or ice.
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.
AMSOIL Synthetic Water-Resistant Grease meets the highest performance standards
set by the National Lubrication Grease Institute (NLGI) for wheel bearing applications
(GC) and chassis applications (LB). It may be used in automotive wheel bearings,
chassis or other applications for which an NLGI No. 2 GC or LB grease is recommended.
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.
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 cleaning and
packing housings with fresh grease on an established maintenance
