Duragard® 100% Synthetic SGC® 634 is an ISO-460 premium synthetic hydrocarbon (SHC) lubricant formulated with advanced Polyalphaolefin (PAO) base oil technology and a very high viscosity index. It is designed for enclosed gear systems, circulating systems, compressors, and hydraulic equipment requiring ashless antioxidant and anti-wear protection. The formulation provides excellent low-temperature flow characteristics while maintaining strong thermal and oxidative stability in demanding operating environments.
Engineered for dependable lubrication, this high-performance synthetic lubricant performs efficiently under hydrodynamic and mild boundary lubrication conditions. Its ISO-460 viscosity grade makes it suitable for gear systems where moderate loads and elevated temperatures are common. The formulation is compatible with components containing soft metals such as bronze and copper and helps maintain smooth and consistent mechanical operation.
Duragard® SGC® 634 is widely used in rotary, centrifugal, and reciprocating compressors, vacuum pumps, high and low pressure hydraulic systems, blowers, enclosed gear units, and circulating lubrication systems. It also performs effectively in splash-lubricated equipment, mist lubrication systems, and applications containing plain or rolling contact bearings.
