In this paper, a seal with triangular cross section was proposed and its performance behavior under compression and various hydraulic pressures was analyzed through experimental and numerical methods. The seal was designed to have a 90 deg corner located near the extrusion gap while hydraulic pressure was applied at an inclination. With this design, it was found that even at hydraulic pressures of up to 18 MPa, the seal offered good fluid tight sealing capabilities without indications of extrusion failures. Such high pressure offers new possibilities for successful application of the seal in aircraft and rocket propulsion equipment. Moreover, the resistance of the seal against leakages was assured because measured contact stresses were greater than applied pressures. A numerical simulation through finite element analysis (FEA) showed that tilting of the delta ring even at angles of did not have any effect on the Von Mises stresses. The FEA results also demonstrated that the deformations and fringe patterns of delta ring were similar to the experimental results.
