DETERMINATION OF STRUCTURAL AND DIMENSIONAL CHANGES OF O-RING POLYMER/RUBBER SEALS IMMERSED IN OILS

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 o-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 mass, thickness and perimeter, swelling test, SEM and oxidation test were done during the period in order to investigate the dimensional and structural changes of rubber seals. The viscosities of immersed oil were also tested to analyze its impact and influence on the physical changes of seals. The analysis was done using the ASTM standard method. Result shows that the Seri Murni Palm Olein has the potential to be used as hydraulic fluid especially when using with VITON seal. However, some of physical and its chemical properties need to be enhanced first such adding additives to the olein in order to improve the effectiveness of the vegetable-based oil as hydraulic fluid.
