Duragard® 100% Synthetic SGC® 634 is an ISO-460 Premium 100% Synthetic Hydrocarbon (SHC),
Polyalphaolefin (PAO)-based Lubricant with a Very High Viscosity Index (HVI) for enclosed gear,
circulating, compressor and hydraulic systems requiring ashless antioxidants and anti-wear
formulations. It has excellent low-temperature flow properties with high thermal and oxidative stability
while providing outstanding lubrication under hydrodynamic and mild boundary lubrication
conditions.

Duragard® 100% Synthetic SGC® 634 is an ISO-460 multi-purpose lubricant for use in gear systems
where moderate loads and high temperatures are expected, including worm gears containing soft
metals such as bronze and copper, provides superior lubrication in rotary compressors, centrifugal
compressors, reciprocating compressors, vacuum pumps, high and low pressure hydraulic systems,
blowers, enclosed gear units, plain and roller contact bearings, circulating and splash lubricated
systems, and mist systems. Be sure to select the correct ISO Grade for your application.
