GRD Rupture Disks


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.
