For the leakage failure caused by the damage of the rubber seal, the cause of the rubber ring damage is analyzed. Through the torsion and rapture of the rubber ring, the problem of thermal shrinkable poly tetrafluoroethylene (PTFE) backup ring heating over shrinkage is found. Finally, this failure is solved by optimizing the design method of the backup ring, including the reserved shrinkage, thickness compensation, etc.
