Fomblin® RT15


Product Overview

Fomblin® RT15 (now known as Klübertemp GR RT 15) is a homogenous white grease suitable for lubricating mechanical parts requiring boundary ( extreme pressure ) lubricating properties.

Shell four ball tests show that Fomblin® RT15 ’s welding point is 800 kg.

Fomblin® RT15’s operating temperature range is from – 20˚C to 200˚C. Its properties make it suitable in ‘lubricating for life’ applications.

  • A few of the critical uses of Fomblin® greases include:
  • Oxygen and chlorine valves and pumping systems,
  • Nuclear industry lubricants
  • Instrument lubricants,
  • Lifetime sealed, maintenancefree bearings.
  • Lubricants for gasoline tank floats.
  • Bearings exposed to high temperatures, moisture and aggressive chemicals.
Features and Benefits
  • Good extreme pressure properties.
  • Wide Thermal range
  • Compatible with elastomers
  • Resistant to solvents
