Kalrez® specialty sealing engineered for your mission-critical applications.

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

While DuPont didn’t invent o-rings or specialty sealants, it has a 40-year track record of innovation and development, creating sealants that stand up to the most challenging operating environments.

Aside from its cleanliness and purity, Kalrez® polymer chains are engineered to be one of the most inert polymer structures available, standing up to more than 1,800 different chemicals while offering high-temperature stability.

Kalrez® perfluoroelastomer parts are manufactured to the highest quality standards. Every part has documented traceability, and these parts provide one of the longest, most predictable lifespans in industry.

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.
