With proprietary compounds for elastomer seals, FMC Technologies prides itself on providing some of the most highly engineered, controlled elastomer seal product lines in the industry. For some applications up to 15,000 psi, elastomer seals can be used in a variety of applications, depending on the elastomeric compound and well environment. Our elastomer seals are qualified to API 6A PR2 (Annex F) requirements, and the majority of our elastomer seal families meet FMC’s pressure and temperature endurance cycle testing requirements, some for sour service. Some seals include anti-extrusion elements, unlike standard O-rings. These anti-extrusion elements, like composite springs, create bubble-tight sealing. They are molded integrally into the seal element, creating an easy installation process and increasing durability.
