Explosive Decompression Resistant FFKM

Explosive decompression, also known as Rapid Gas Decompression (RGD) or Anti-Explosive Decompression (AED), is one of the most critical failure modes in high-pressure sealing systems. When elastomers are exposed to high-pressure gases, those gases can permeate into the material. If pressure is released too quickly, the trapped gas expands rapidly, causing internal blistering, cracking, and catastrophic seal failure.


FFKM (perfluoroelastomer) O-rings, gaskets, custom parts, and tubes are specifically engineered to resist these effects in demanding environments such as oil & gas, chemical processing, and high-pressure gas systems. At Canyon Components, Canrez® FFKM AED-resistant compounds are designed to provide enhanced RGD resistance, excellent chemical compatibility, and long-term sealing performance, even under aggressive pressure cycling conditions.


In many applications, compliance with standards such as API 6A, NACE TM0297 and NORSOK M-710 is required to validate performance in decompression environments. Canrez® FFKM materials are available in compounds designed to meet these requirements, while offering strong availability and competitive pricing compared to Kalrez® and Chemraz®. Canyon Components engineers work closely with customers to ensure the correct combination of material selection, durometer, gland design, and backup ring integration for optimal performance in AED applications.


Common names include: FFKM, Perfluoroelastomer, Perfluorinated Rubber. Trade names: Canrez®, Kalrez®, Chemraz®, Simriz®, Parofluor®.

Features of AED / RGD Resistant FFKM O-Rings, Gaskets, & Custom Parts


  • FFKM perfluoroelastomer materials exhibit reduced gas permeation and improved structural integrity under high-pressure gas exposure


  • High durometer FFKM compounds (typically 85 Shore A and higher) improve resistance to deformation and internal damage during decompression




  • FFKM O-rings, gaskets, and custom parts maintain low compression set, ensuring long-term sealing performance under pressure cycling


  • Designed for use with optimized gland geometries and optional backup rings to enhance anti-extrusion performance


  • Available in standard sizes, custom molded parts, large diameter seals, and complex geometries for demanding applications


  • Canrez® FFKM offers strong availability and cost efficiency compared to Kalrez® and Chemraz® AED-resistant materials

Limitations of AED / RGD Resistant FFKM O-Rings, Gaskets, & Custom Parts

  • FFKM O-rings, gaskets, and custom parts have a higher upfront cost compared to standard elastomers, though lifecycle performance is often superior


  • AED performance depends heavily on compound selection, durometer, and application conditions, requiring careful engineering evaluation


  • High-pressure systems may require backup rings and precise groove design to prevent extrusion and optimize seal life


  • Qualification to standards such as NACE and NORSOK depends on specific test conditions and compound performance


  • In extreme pressure or decompression scenarios, alternative sealing technologies such as PTFE spring energized seals or metal seals may be considered
