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.
