Extruder Pressure Plugs (Burst Plugs/Rupture Disk)
Extruder pressure 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.
Extruder pressure plug 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 offer 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”.
