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.
When a valve's fugitive emission and process control performance are critical, let Kalrez® KVSP™ packing systems using Kalrez® perfluoroelastomer parts eliminate your emission problems and improve process control.
Kalrez® slabs and sheets are available in several sizes and compounds, providing many options to use Kalrez® as a flexible sealing solution.
Bonded door seals made with Kalrez® 9100, 8002 and Kalrez® Sahara™ 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.
DuPont has developed elastomer 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.
