Extensively tested beyond API’s most stringent requirements, all of FMC’s metal seals are qualified to meet a wide range of applications. With a 0% gas leakage acceptance rate, and bubble-tight sealing requirements, they are designed for 2,000-20,000 psi. We test our metal seals beyond API 6A PR2 because we believe in our designs. We feel that the engineering and research poured into each seal’s development are necessary elements for success.
