Kalrez Seals for Extreme Service

Stable in Harsh Environments

From aerospace and chemical processing to chip manufacturing and oil and gas applications, DuPont™ Kalrez® elastomers are engineered to provide more stability, more resistance, and more effective sealing.

Kalrez ®: the No.1 seal for extreme service

Kalrez ® parts match the chemical resistance and high temperature stability of PFTE, while adding the resilient, no-creep properties of a true rubber. There is no other rubber sealing material which can perform this well for such extended periods in such aggressive environments.

The advantages of Kalrez ® Parts:

  • Kalrez ® parts last longer and perform better than other elastomers
  • Reduces the risks of seal failure
  • Increases safety
  • Increases productivity
  • Reduces maintenance costs
  • Resistant to more than 1800 chemicals
  • Retains its sealing force longer than other elastomers

Applications:

  • Chemical Processing
  • Analytical and process instruments
  • Semiconductor manufacturing operations
  • Energy production
  • Aircraft and aerospace industries
  • Pharmaceutical and food processing
  • Hydrocarbons or highly corrosive fluids, or when a wide range of temperatures is encountered

The long-term, proven performance of Kalrez® parts can mean less frequent seal changes, repairs, and inspections, increasing process and equipment uptime for greater productivity and yield.
