DuPont™ Kalrez® TriLobe™

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 process chemicals.

• Seal design and compound selection combine to yield REDUCED PARTICLE GENERATION and SIGNIFICANTLY INCREASED SEAL LIFE!

Suggested Applications

• Slit valve doors

• Gate valves

• Semi-dynamic sealing applications that utilize a dovetail groove configuration

Availability

• 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.

• The Kalrez® TriLobe™ seal is available in a variety of compounds. DuPont or its authorized distributors can help you determine the best compound to optimize seal performance for your set of process conditions.

• Contact an authorized distributor of Kalrez® parts for pricing and availability.
