Sustainable Aviation Fuels (SAF) are being tested as a 100% replacement for petroleum fuel by the aviation industry as a commitment to reducing carbon emissions. Embraer successfully completed experimental flights with commercial and executive jets using 100% SAF. The literature indicates that the lack of aromatic compounds in SAF impacts the adequate sealing of nitrile elastomers and, if they have been previously exposed to conventional aviation fuel, recommends replacing them with new ones before refueling with 100% SAF. This study evaluated the volume variation in nitrile rubber O-rings when immersed in fuel, alternating between HEFA-SPK and Jet A.
