Kalrez® perfluoroelastomer parts

Oil and Gas Seals

Perfluoroelastomer Resistant To Rapid Gas Decompression

Kalrez® perfluoroelastomer parts stand up to severe down-hole conditions from high pressures and temperatures, to aggressive sour gas and corrosive fluids. Down-hole conditions can deteriorate elastomers rapidly. Blistering heat, corrosive fluids and toxic gases can destroy the physical properties and sealing performance of other materials. Even under extreme conditions of pressure, heat and manmade chemicals, Kalrez® oil and gas seals have held up and remained virtually unchanged. Kalrez® has been field-proven across the industry in such applications as:

oil and gas seals
  • Tubing-to-packer seals
  • Subsurface safety valves
  • Logging boots
  • Casing tie-back seals
  • Survey tool seals
  • Slip-joint seals

Kalrez® is offered in standard or specialty compounds that have been formulated to optimize properties and give the best performance in specific applications. In rigorous third-party testing for rapid gas decompression (RGD) resistance, Kalrez® 0090 O-rings, received the best possible rating of 0000 per the NORSOK M-710 Rev 2 standard.
