ICON™ Rupture Disc

Protect intermodal tank containers, railroad tank cars and tank trucks with the ICON rupture disc – a tension-acting, cross-scored, non-fragmenting disc designed for the unique demands of liquid and gas transportation vessels.

The ICON rupture disc is ideal for installation beneath pressure relief valves due to its non-fragmenting design.

ICON rupture discs protect nearly every type of transportation vessel – road, rail or naval shipping – from potentially damaging overpressure conditions. The ICON bursting disc is ideal for installation beneath pressure relief valves due to its non-fragmenting design.

ICON and ICON-TL rupture discs have all the same performance features, but we’ve fully fluoropolymer-lined the ICON-TL on all wetted surfaces, making it ideal for applications involving highly corrosive media.

The ICON and ICON-TL are:

  • High-quality – manufactured from a single sheet of metal, then scored and tested
  • Long-lasting – polished smooth on the process side to prevent any process media accumulation
  • Corrosion-resistant – due to fluoropolymer liners on the process side of the disc
  • Self-aligning – an outlet ring assures proper positioning with the valve or mating outlet flange
  • Reliable – capable of withstanding full vacuum without vacuum support
  • Leak-tight – inlet and outlet fluoropolymer gaskets seal the system
  • Non-fragmenting – ideal for isolating pressure relief valves
