We design and engineer high-precision welded rupture disc assemblies for use in extreme operating conditions found in aerospace and defense technologies.
Each solution is flexibly designed to meet your specific performance, environmental, and compliance requirements. Our assemblies are trusted to deliver accurate, reliable, repeatable performance in demanding applications around the world – and in space.
Trusted in High-Risk Aerospace and Defense Systems
Our custom welded rupture discs are used across mission-critical systems, including lithium-ion battery protection in spaceflight and subsea vehicles, pressure activation in propulsion systems, and life-saving crew safety equipment.
- Built for harsh environments, our assemblies are corrosion-resistant and leak-tight, guaranteeing absolute containment until activation. When the defined pressure is reached, they activate within milliseconds, enabling split-second responses for life-support systems and propulsion equipment.
- They can withstand extreme temperatures, pressures, and rapid changes in pressure and altitude. This includes proven performance at cryogenic temperatures, including liquid helium, for spaceflight and propulsion applications.
- They deliver reliable, fail-safe performance under vibration, shock, acoustic loads, and thermal cycling.
Fully Tested and Documented for Qualification Confidence
Quality and compliance are integrated into every stage of design and manufacture. All rupture disc assemblies are fully tested, rigorously inspected, and completely traceable. We provide full certification and documentation to support qualification, project requirements, and applicable aerospace, defense, and industrial standards.
