TANKSERT Rupture Disc

Liquid and gas transportation operations need the TANKSERT rupture disc – a composite rupture disc that protects railroad tank cars, over-the-road tank trucks and other vessels from dangerous overpressure conditions.

The TANKSERT rupture disc is ideal for installation in standard threaded- or bolted-type safety vent assemblies on transportation vessels.

The TANKSERT rupture disc is a composite type, with a flat seat sealing configuration. It fits both threaded- and bolted-type safety vent assemblies. It features:

  • Self-aligning vacuum support to assure proper positioning in the safety vent assembly
  • Vacuum support to prevent seals from becoming damaged should a pressure surge occur during transit or unloading
  • Capability to withstand full vacuum
  • A non-fragmenting design
  • Inlet fluoropolymer gaskets for a leak-tight seal
  • Optional #14 or #20 bee screens to protect openings from insects or airborne particles after a disc ruptures
  • Overpressure protection, no matter the vessel

We offer an array of rupture disc products designed to protect railroad tank cars, intermodal tank containers, tank trucks, over-the-road tank trucks and nearly any other vessel that transports liquid or gas products. If TANKSERT isn’t what you’re looking for, we recommend the ICON rupture disc.
