Explosive decompression happens when trapped high-pressure gas inside an elastomer rapidly expands, causing blistering, cracking, and sudden seal failure. Choosing ED-resistant compounds, correct groove design, and AED-rated O-rings and gaskets reduces the risk of catastrophic leaks in oil and gas, downhole, and high-pressure pneumatic systems.

What Is Explosive Decompression in O‑Rings (AED) and How to Prevent It

Backup rings prevent extrusion and extend the service life of O-rings in high-pressure or wide-clearance sealing applications. Available in PTFE, nylon, and other durable materials, they ensure reliable performance in static and dynamic hydraulic or pneumatic systems.

NORSOK M-710 | Ensuring Material Quality in Oil and Gas

Anti-explosive decompression (AED) materials prevent blistering, cracking, and failure of elastomer seals when exposed to rapid pressure drops in high-pressure gas environments. Commonly used in oil and gas, aerospace, and energy applications, they ensure long-term sealing integrity and safety under extreme conditions.
