GRD Rupture disks



  • Ranges from 2500 psi (170 bar) to 12000 psi (827 bar)
  • Rated to 750°F (400°C)
  • Two length options
  • Low installation and maintenance
  • Stainless-steel body and Inconel diaphragm (disk)


  • Rupture disks, also known as burst plugs or soft plugs, are used for emergency pressure relief of an extruder
  • They are designed to instantaneously rupture at a specific pressure
  • This provides reliable relief in applications where rapid pressure buildup can occur, protecting both personnel and equipment
  • For maximum life, the recommended pressure rating is >=1.4 times normal operating pressure
  • Do not exceed the high-pressure specification
