FR® 58/90

High performance elastomer for applications with risk of rapid gas decompression on larger section seals.

  • Oil & Gas
  • Valves

The benchmark FKM for over 30 years, this is a good cost-effective general purpose fluoroelastomer (FKM) providing excellent resistance to rapid gas decompression (RGD) at larger cross sections and higher temperatures, this material also provides the resistance to H2S and aromatics typical of an FKM.

  • Low temperature: sealing capability confirmed down to -33°C (-27°F) in product configured testing
  • TR10 -14°C (+7°F)
  • T70 -12°C (+10°F)
  • High temperature: continuous +210°C (+410°F)

  • API 6A FF/HH ISO 10423 ‘sour’
  • Norsok M-710 Annex A ISO 23936-2 ‘sour’
  • Norsok M-710 Annex B ISO 23936-2
  • Total GS EP PVV 154/156

Norsok M-710 Annex B ISO 23936-2

  • ‘0000’ rating at +100°C 5.33 mm / 150 bar / 90% CH4 10% CO2 / 8 cycles
