AB  - The purpose of this work is to investigate the suitability use of vegetable-based oil in hydraulic system and the compatibility between the rubber seals and lubricant extracted from vegetable-based oil in hydraulic system. Two types of a-ring rubber seals were used which are VITON and NBR. These rubber seals were fully immersed in two different types of oil, Seri Murni Palm Olein and Pennzoil 68 Hydraulic Oil for two months. Detailed analysis of the rubber seals weight, thickness and perimeter, swelling test, oil viscosity, SEM and oxidation test were done during the period in order to investigate the dimensional and structural changes of rubber seals. Result shows that the Seri Murni Palm Olein has the potential to be used as hydraulic fluid especially when using with VITON seal. However, additives should be added to the olein in order to improve the effectiveness of the vegetable-based oil as hydraulic
fluid.
