A X‐ring is a loop of elastomer with X‐shaped cross‐section used as a mechanical seal or gasket. Such a X‐ring is designed to be seated in a groove and is compressed during assembly between two or more parts, creating a seal at the interface. The seal is designed to have line contact between the X‐ring and sealing faces. This allows a high local stress, able to contain high pressure, without exceeding the yield stress of the X‐ring shell body. This study aims to detect the contact stress and the deformed shape of a X–shaped ring shell under various compression conditions. For this analysis, four experiments were conducted to obtain material properties of the elastomer. The contact stress analysis is performed by applying material properties that we obtained through experiments. A contact stress analysis is carried out by finite element analysis.
