AMSOIL Synthetic Fifth Wheel & Open Gear Compound
Synthetic Fifth Wheel & Open Gear Compound (GFW)

Stays in place and protects over a broad temperature range without
flaking in low temperatures or softening in high temperatures.
Excellent for fifth wheel applications, with a convenient aerosol
spray application that creates less mess. Designed to resist water
washout. Can also be used in open gear applications.
Package sizes include:

11.5-oz Spray Can
11.5-oz. Spray Cans (case of 6)
PRODUCT DESCRIPTION
AMSOIL Synthetic Fifth Wheel and Open Gear Compound (GFW) is based on proprietary
technology resulting in a lubricant that does not use asphaltic materials, residual compounded oils
or diluent solvents as part of the lubricant formulation.* Typical gear compounds are composed of
asphaltic and residual oils cut with solvent to ease application and use. Synthetic GFW does not
require solvents to assist the product in application and use, even in cold weather.

*Aerosol spray contains a solvent that evaporates quickly leaving a solvent-free film of material on
treated surfaces.

WIDE OPERATING TEMPERATURE RANGE
AMSOIL GFW performs well in cold temperatures and won't drip off at high temperatures, reducing
the need for frequent rlubrication.

ADHESION TO METAL
AMSOIL GFW provides excellent adhesion to metal surfaces in cold and hot temperatures.
Tackiness allows it to stay in place in high-speed applications, even when applied to open gears or
chains. Spray formulation offers quick and easy application.

WATER WASHOUT RESISTANT
AMSOIL GFW repels water, protects metal parts from rust corrosion and stays in place to protect
gears from wear.

HANDLES HEAVY LOADS
AMSOIL GFW provides a tough grease film to handle heavy loads and prevent metal parts from
contacting.

PERFORMANCE FEATURES
  • Excellent resistance to water washout
  • Environmentally preferable to solvent-containing formulations
  • Protects ferrous surfaces from rust
  • Excellent adhesion to metal surfaces
  • Forms a tacky, tenacious film
  • Heavy load-carrying and extreme-pressure performance
  • Stays pliable at cold temperatures and does not flake off

APPLICATIONS
AMSOIL GFW may be applied to fifth-wheels, open gears, chains, flexible couplings, sliding
surfaces of drag lines and shovels, construction equipment, dredging equipment or any application
where a heavy, tenacious lubricant is required.

Performance Data
AMSOIL Synthetic 5th Wheel and Open Gear Compound meets the AGMA 14R and NLGI #1
performance specifications.

Installation
AMSOIL Synthetic 5th Wheel and Open Gear Compound is fully compatible with other fifth-wheel
and open gear compounds and may be applied to surfaces previously treated with other fifth-wheel
and open gear compounds.
