This study focuses on interaction and compatibility between hydraulic oil and Seal. These interactions are carried out by experiments based on Korean Industrial Standard. The mineral hydraulic oil and synthetic hydraulic oil based on HEES(Hydraulic Environmental Ester Synthetic) were used in the experiments. Specimen is NBR and polymer plastic that material for low friction seal. Design factors are time, temperature and moisture content rate. In addition, it analyzed variations of characteristics of hydraulic oil and Seal. For example, characteristics of hydraulic oil are viscosity and TAN and those of Seal are tensil strength and elongation. The experiemtn results are as follows Hydraulic oil and polymer plastic were showing positive characteristic changes, whereas NBR was not.
