Screw Type Holder Assembly

The LaMOT Brand Products Screw Type Assembly is a reusable unit for use in systems with pressures up to 15,000 psig (1,034 barg). A Standard Rupture Disc or Composite Rupture Disc is supplied separately from the Screw Type Holder. After an overpressure condition occurs, changeout is accomplished by disassembling the Screw Type Holder and replacing only the burst rupture disc.

The Screw Type Assembly is a flat seat design, configured with a 1/2" Standard, 11/16" Standard or 11/16" Composite flat seat rupture disc. This assembly is used primarily for laboratory applications and in other small pressure vessels or systems.

The Screw Type Holder is available with the inlet, outlet and holddown ring made from brass or 316SS. Specify the required material when ordering.
