Price Guide (Inc GST): POA

SR and XL Series Rupture Disc Holders have been designed to provide the following features:

  • DiscLocTM locator helps prevent inverted disc installation
  • Serrated gasket faces per ANSI B16.5 for improved gasket sealing
  • Optional O-Ring disc seal for reduced emissions
  • Optional 1/4" or 1/2" Gauge tap for installation of pressure gauges*

Note: * 1/2" Gauge Tap not available in 1 1/2" and 2" 150 ANSI TQ or 1-1/2" 300 ANSI TQ sizes


The "GI" insert rupture disc holder consists of a base (inlet) and a holddown flange (outlet). 300 series stainless steel sideclips are provided to facilitate preassembly of the rupture disc prior to installation.


The pretorqueable rupture disc holder consists of a base (inlet) and holddown flange (outlet) with pretorqueable capscrews to provide proper clamping of the rupture disc. The correct load is applied to the assembly using the standard socket head capscrews provided with the holder assembly.

The purpose of this holder design is to allow the rupture disc to be installed and torqued to the proper static load values at a workbench under ideal conditions. It may then be delivered to the field location to be installed between companion flanges.

The pretorqueable feature eases field assembly work during installation between companion flanges and reduces the possibility of errors causing leakage.

Pretorqueable assemblies may also be removed, inspected and replaced during routine maintenance schedules and plant turn-arounds without compromising disc performance.
