Rapid gas decompression resistance is mandatory for API 6A seals. Top compounds include Seals Eastern 7182 (Viton ETP), Daemar DMR-HNBR, and Solvay Tecnoflon PFR FFKM. Tested per NORSOK M710 at 150 bar/min decompression, these seals show zero cracking after 10 cycles, preventing explosive seal failure in high-GOR wells. https://globalsealstech.com/
