LUBRICATING OILS, DI-ESTER Chemical compatibility with O-rings, rubbers, & plastics

Diester based lubricating oils are synthetic lubricants formulated from diester compounds and are widely used in aviation systems and high performance industrial equipment. These lubricants offer strong thermal stability, oxidation resistance, and reliable lubrication across a wide temperature range. In machinery where the oil contacts O-rings, rubber seals, gaskets, and plastic components, compatibility should be evaluated to prevent swelling or degradation of sealing materials. Although highly effective, proper storage, careful handling, and routine system maintenance are important to maintain lubrication performance and operational safety.
