combination.

#### Application notes

In general, Klüberbio RM 2 oils are miscible with mineral oil based stern tube lubricants. However, a miscibility test should be performed in order to totally rule out the possibility of an incompatibility between different additives. Prior to changeover, we recommend flushing the stern tube with the Klüberbio RM 2 oil.

Klüberbio RM 2 oils need to be approved by the OEMs of your propeller shaft seal or bearing. In case the oil has not yet been approved or the specification of the seal or bearing has been changed – e.g. type, design or material – we recommend consulting the OEM prior to the oil change.

Owing to the many different elastomer compositions of seals we recommend – prior to series application – checking the compatibility and other influencing factors that are relevant for the application with the component under conditions similar to practice.
