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.
Features and Benefits
• Molded notch makes installation a snap!
• Reduces installation time.
• Avoids improper installation.
• Geometry interlocks in groove to prevent seal from rolling and twisting during installation.
• Bottom lobes lock seal in place to resist pullout and movement during actuation.
• Seal parting lines are maintained below the flange surface, eliminating direct exposure to plasma or
• Seal design and compound selection combine to yield REDUCED PARTICLE GENERATION and
SIGNIFICANTLY INCREASED SEAL LIFE!
• Slit valve doors
• Gate valves
• Semi-dynamic sealing applications that utilize a dovetail groove configuration
• Molds have already been developed for a number of common slit valve door seal part sizes.
• A DuPont Kalrez TriLobe seal can be developed to fit any size dovetail groove.
