GST® Oil
Premium Performance Industrial Gas & Steam Turbine Oil

- • non-geared gas, steam, and hydroelectric turbine bearing lubrication
- • reduction gear lubrication in marine operations
GST Oils are formulated to meet the demands of non-geared gas, steam, and hydroelectric turbine bearing lubrication, and reduction gear lubrication in marine operations. They are an excellent recommendation for many other industrial applications including air compression where R&O type oils are recommended.
GST Oil 32, 46, 68, 100 are registered by NSF and are acceptable as lubricants where there is no possibility of food contact (H2) in and around food processing areas. The NSF Non-food Compounds Registration Program is a continuation of the USDA product approval and listing program, which is based on meeting regulatory requirements of appropriate use, ingredient review and labelling verification.
GST Oils help deliver value through:
- Exceptional oxidation stability, helping provide long service life at elevated temperatures. Formulated with premium base oil technology and an ashless, zinc-free formulation.
- Rust and corrosion protection
- High viscosity index, helping ensure minimal viscosity change when variations in temperature occur.
- Minimal foam, helping prevent sump overflow and erratic governor operation.
- Fast air release, minimizing possibility of pump cavitation in systems with high circulation rates and small reservoirs.
- Exceptional thermal stability, minimizing deposit formation.
- Rapid water separation, helping keep water in oil to a minimum.
- Hydraulic fluid service — GST Oils 32, 46 and 68 are excellent hydraulic fluids in low pressure systems up to 1000 psi.
- Air compressor lubricant when OEM recommends R&O type oil.
