DuPont™ Kalrez® Sanitary Seal Applications


Kalrez LS390 Ferrule

The DuPont™ Kalrez® LS390 provides longer seal life and tighter sealing, which improves productivity and process optimization as well as creating a safer environment in the day to day running of a pharmaceutical manufacturing facility.

Sanitary seal applications can often experience problems related to thermal and chemical resistance , compression set (permanent deformation). The Kalrez® LS390 overcomes these issues with its high hardness properties, low friction, high temperature resistance (428F), and broad chemical resistance.

DuPont™ Kalrez® parts last longer and seal more effectively than other elastomers in demanding processing environments.  The long term proven performance of Kalrez® parts can mean less frequent seal changes, repairs and inspections, increasing process and the equipment's up-time for greater productivity and yield.
