  • Lubricants
  • Lubricants & Sealants
  • Valve Lubrication

Desco 990-GT is a water insoluble synthetic valve lubricant and anti-seize for use in extreme high temperature environments such as geothermal applications. It is highly resistant to water
and aqueous solutions (alkalis, acids). The solid lubricant additives contained in Chemola™ Desco 990-GT allow a greater degree of lubrication at temperatures where most lubricants fail.

Service Recommendations:
Geothermal, steam, kiln car bearings and forging operations.
