Elastomer seals in fuel systems have to evince required mechanical properties also at exposure to fuels. The aim of the research was to determine an influence of various concentrations of rapeseed methyl ester (RME) on a change of mechanical properties of sealing O-rings made from polyacrylate elastomer (an indication ACM). A permanent deformation - compression set (CS), a tensile strength and an elongation after the exposure to the tested environment for the time 20 months were evaluated within the experiment. A fall of the tensile strength, the elongation and the permanent deformation - compression set CS was proved depending on the type of the fuel. The increased negative influence of various concentrations of RME (20% to 100%) on the tested properties of the sealing O-rings compared with the diesel oil complying with the standard EN 590:2004 was not proved. So a significant negative influence of degradation aspects on the tested properties of the O-rings of the ACM type (polyacrylate elastomer) was not proved.
