Rupture Disk Extruder (Burst Plugs) are primarily used on Plastics Extrusion Machinery to provide emergency pressure relief. They are designed to instantaneously rupture at a pre-determined pressure. They are leak tight and intrinsically safe devices that require no maintenance.

Burst Plugs assemblies are manufactured from 304 SS and incorporate either an Inconel or Stainless Steel Disk which minimize the affects of varying processing temperatures. The RD Series of Burst Plugs are offered in a wide variety of lengths and configurations. Standard stock assemblies are available in burst pressures ranging from 1,500 up to 15,000 psi, and lengths from 1.82” up to 12”.

Several different mounting threads are offered on the RD Series Burst Plugs that are commonly found on plastics extrusion machinery.
