Special grease for elastomers and plastics
Application Klüber Klüberbeta RM 47-291
Klüberbeta RM 47-291 is primarily used for the lubrication of sealing elastomers. In such applications it attains minimum friction coefficients even at low temperatures. The product also shows good compatibility with a multitude of materials and good stability at high temperatures. Exemplary fields of application are O-ring seals in pneumatic equipment in cars.
Performance, Features & Benefits of Klüber Klüberbeta RM 47-291 are:
- Longer component life due to low friction coefficients across a wide service temperature range
- GLonger component life due to good compatibility with elastomers and plastics
- Simple handling enabled by good wetting of functional surfaces

Product Description Klüber Klüberbeta RM 47-291
As a manufacturer of pneumatic systems you expect valves to operate smoothly at both high and low temperatures. You therefore need a grease that is compatible with the materials used and also has a wide service temperature range. Klüberbeta RM 47-291 is a special grease enabling smooth component operation at low temperature and offering high thermal stability. It is based on silicone oils and contains a lithium soap thickener. Due to its specific consistency, it shows good backflow behaviour into the lubrication gap. Its shows notably good compatibility with many elastomers (except silicone rubber) and plastics.
