Description

Rupture discs engineered for ultra-high pressure applications. They deliver predictable burst behavior, controlled opening characteristics, and traceable burst testing. For example, these discs suit high-pressure labs, oilwell cementing, specialty reactors and other extreme-pressure systems. Before selecting one, please review pulsation, impact loading, cycling and media compatibility with your application engineer.

Product at a glance


  • Burst range: Customizable — we offer setpoints from low pressure up to ultra-high ranges. In particular, specialized models exist that are rated from hundreds to thousands of bar.
  • Material: Tempered or chemically strengthened glass, or glass-composite elements; you can add metal backing or composite assemblies to control fragments.
  • Repeatable & verifiable: Our factory performs burst tests and issues a burst certificate that shows the test curve and batch traceability.
  • Application fit: Designed for high-pressure laboratory rigs, oil & gas downhole cementing and stimulation, high-pressure reactors and aerospace test benches.
  • Standards & compliance: We size and specify per ASME and industry rupture disc guidance (ASME/API). Also, we provide installation torque and seat selection guidance.

Why choose a tempered glass rupture disc?


  • Predictable fracture mechanics: We engineer glass elements to fracture in a controlled pattern. When paired with the correct backing and containment, they produce low fragment dispersion.
  • Contamination control: Because glass does not shed metal debris, glass-based burst elements reduce metallic contamination risk in sensitive chemical, pharmaceutical or optical processes.
  • Visual verification: You can visually confirm fracture. Moreover, certain designs serve as an optical inspection window until the moment of burst.

Important: Tempered glass rupture discs represent a specialized solution. Therefore, confirm pulsation, impact loading, cycling and media compatibility with your application engineers before selection.
