Extruder Rupture Discs (Burst Plugs)

Product Overview

ONEhalf20 Extruder Rupture Disks (Burst Plugs) are primarily used on Plastics Extrusion Machinery to provide emergency pressure relief.

More Information

Extruder Rupture Disks from ONEhalf20 are designed to instantaneously rupture at a pre-determined pressure. Extruder Rupture Disks are leak tight and intrinsically safe devices that require no maintenance.

ONEhalf20 Extruder Rupture Disk 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 Extruder Rupture Disks from ONEhalf20 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 ONEhalf20 RD Series Extruder Rupture Disks that are commonly found on plastics extrusion machinery.
