Compression set resistance defines long-term sealing reliability in FFKM applications. Premium grades exhibit less than 15% set after 70 hours at 300°C, compared to 50–80% for standard FKM. This property ensures bolt load retention in flange connections and valve stems over years of thermal cycling. Low compression set directly translates to extended maintenance intervals and reduced ... https://globalsealstech.com/ffkm-seals/
