Description
DuPont has developed a seal design to improve seal life in dovetail grooves. This design combines the
excellent chemical, thermal and plasma resistance of DuPont™ Kalrez® perfluoroelastomer parts with a
unique cross-sectional shape that eliminates many of the problems associated with semi-dynamic seal
applications using a dovetail groove. These problems include installation difficulties as well as short seal
life and particle generation due to seal wear and degradation.
