Challenging Field Environments

Kalrez® perfluoroelastomer parts stand up to severe downhole conditions--from high pressures and temperatures, to aggressive sour gas and corrosive fluids. Downhole 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 man-made chemicals, Kalrez® seals have held up and remained virtually unchanged. Kalrez® has been field-proven across the industry in such applications as:

  • 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 grades that have been formulated to optimize properties and give the best performance in specific applications.
