Kalrez Seals

Seals made from Kalrez  are high-performance elastomeric seals.  The material is manufactured only by DuPont™. These seals are made from a perfluoroelastomer material, which can resist over 1,800 different chemicals while maintaining the high-temperature stability of PTFE (327°C). The properties of the material help maintain seal integrity, reduce maintenance and operating costs, and improve safety. This makes them ideal for mission-critical applications, such as aerospace, automotive, and chemical processing.  Kalrez seals are expensive and not readily available.  Independence Seal can offer alternatives to Kalrez material

Features of Kalrez Seals

There are several reasons to invest in the replacement seals made with Kalrez material. Here are some of them:

• Advanced Material Composition: Kalrez seals are made from perfluoroelastomer (FFKM), a high-performance material renowned for its exceptional chemical resistance and stability in extreme environments. This makes it ideal for demanding applications.
• Wide Temperature Range: These seals can withstand a broad temperature range from -20°C to 327°C (-4°F to 620°F), offering reliable sealing performance in both low- and high-temperature environments without degradation.
• Exceptional Chemical Resistance: Kalrez seals provide excellent resistance to a wide range of aggressive chemicals, including acids, bases, solvents, and gases. This makes them ideal for industries that handle highly corrosive or hazardous substances.
• Custom Design Options: Available in various shapes, sizes, and configurations, such as O-rings, gaskets, and custom-engineered solutions, Kalrez seals can be tailored to meet the specific requirements of different applications, ensuring optimal sealing performance.
• High-Pressure Resistance: These seals are designed to withstand high-pressure environments without compromising their sealing integrity, ensuring long-lasting performance even in the most demanding conditions.
• Minimal Compression Set: Kalrez seals maintain their sealing properties over extended periods, even under extreme temperatures and pressures. Their minimal compression set prevents leakage and ensures consistent sealing performance over time.
• FDA and USP Compliance: Certain grades of Kalrez seals meet the stringent standards of FDA and USP Class VI, ensuring their suitability for use in sensitive industries such as food processing, pharmaceuticals, and medical applications.
• Long Service Life: Due to their exceptional durability and resistance to wear and tear, Kalrez seals provide an extended service life, reducing the need for frequent replacements and minimizing operational downtime.
