DuPont has developed a unique seal design to improve seal life in dovetail grooves. This design benefits from the excellent chemical, thermal and plasma resistance of DuPont™ Kalrez® perfluoroelastomer parts with a unique cross-sectional trilobe seal 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.
