Introducing a New Standard of Cleanliness and Sealing Efficiency for Pharmaceutical Process Lines

Selecting joint design and sealing material in process lines for the optimum balance of cleanliness and seal life is an ongoing challenge to the pharmaceutical process engineer. DuPont Performance Elastomers now answers that challenge with a new developmental Sanitary Seal design, a combination of two optimum performance engineering materials stainless steel and Kalrez®.

  • Stainless steel and Kalrez® parts provide premium performance in CIP and SIP applications.
  • Meets ASTM requirements for CIP and SIP application.

Selecting joint design and sealing material in process lines for the optimum balance of cleanliness and seal life is an ongoing challenge to the pharmaceutical process engineer.

DuPont Performance Elastomers now answers that challenge with the new Kalrez® Sanitary Seal, a combination of two optimum performance engineering materials stainless steel and Kalrez®. Developed to provide the cleanliness of PTFE and the elastic memory of an elastomer, this seal is designed with a metal retainer that controls compression of the seal and prevents its intrusion into the process stream. The Kalrez® sealing element minimizes absorption, desorption and extractables to assure minimal contamination and a long sealing life.
