Klübertemp GR UT 18N Vacuum Grease –
Temp Range (-30 to +230 (°C))

High-temperature multi-purpose grease


Klübertemp GR UT 18N is a white, odourless high-temperature multipurpose grease based on a perfluorinated polyether (PFPE) oil and a polytetrafluoroethylene (PTFE) thickener. The base oil viscosity enables a wide variety of applications to be served over a wide operating temperature range (peak temperature 250°C).

Klübertemp GR UT 18N shows a neutral behavior towards most plastics and elastomers and can therefore be used for a variety of component materials.


  • Multiple uses over a wide operating temperature range
  • Good resistance to aggressive media
  • High thermal stability
  • Neutral towards plastic materials


Klübertemp GR UT 18N is used in numerous sectors of industry and a wide variety of components in high- and low-temperature applications requiring medium base oil viscosity.

Application examples are

  • Precision engineering
  • Special appliance industry
  • Rolling and plain bearings
  • Plastic/plastic material combinations
  • Lubrication of seals

Behavior towards elastomers and plastics

Lubricants based on perfluorinated polyether oils and polytetrafluoroethylene are generally regarded as neutral towards most elastomers and plastics (exception: perfluorinated rubber).

Nevertheless we recommend testing compatibility with the material to be used, especially prior to series application.

Application Notes

For optimum lubrication results, we recommend cleaning the friction points with white spirit 180/210 followed by Klüberalfa XZ 3-1. Then blow the surfaces with clean, dry compressed air or hot air to remove solvent residues. For initial lubrication, the friction points must be clean and bright, i.e. free from oil, grease and perspiration). Klübertemp GR UT 18N is applied directly or by means of brush, spatula or lubricant dispenser. The technical sales departments at Klüber Lubrication may be contacted at any time for advice to ensure optimum service life results.

Shelf Life

It is strongly recommended using all fluids and greases at the time of receipt, however when storage is necessary, rotate older stock into use first and observe the recommended parameters listed below.

Klüber Grease

Shelf Life of Klüber Grease is a minimum of 5 years; in this case although there won't be problems in terms of chemical stability there can be oil separation over time, which is normal.
