RGD
and sour

An excellent cost-effective general purpose fluoroelastomer (FKM) providing outstanding resistance to rapid gas decompression (RGD) at larger cross sections and higher temperatures, this material also provides the resistance to H2S, aromatics and hot water typical of an FKM.

Vermilion Four is a next generation development of James Walker FR58/90.

Sealing capability confirmed down to -33°C (-27°F) in product configured testing.
