DuPont™ Kalrez® custom elastomer seals are designed and molded to your specific requirements. Typical custom perfluoroelastomer (FFKM) shapes include valve seats, diaphragms, gaskets, packer seals, T-seals, column fittings and more.
Custom parts and components with unusual geometries can be designed and molded in Kalrez® perfluoroelastomer parts to meet the needs of specific sealing applications. Examples include special profiles and rectangular-shaped seals for slit valves and windows: metal-bonded parts, profiled quartz tube seals, diaphragms, lip seals, hollow O-rings, tubing and other specialized configurations.

Bonded Door Seals
Bonded door seals made with Kalrez® 9100, 8002 and Kalrez® 8085 for gate valves and slit valve door seal applications provide improved sealing performance versus conventional O-rings by reducing particle generation, extending seal life and minimizing replacement time during preventive maintenance.

Kalrez® TriLobe™ Seals
DuPont has developed Kalrez® TriLobe™ Seals to improve seal life in dovetail grooves. This design combines the excellent chemical, thermal and plasma resistance of parts made with Kalrez® perfluoroelastomers, with a unique cross-sectional shape that eliminates many of the problems associated with semi-dynamic seal applications using a dovetail groove.
