DuPont to Showcase Kalrez® Advanced Sealing Solutions at Valve World 2025

Featured Products Include Kalrez® Custom Shapes and Valve Stem Packing

Wilmington, Del., June 3, 2025 – DuPont (NYSE: DD) is proud to announce its participation in Valve World Americas, taking place June 4-5 in Houston, Texas. At booth 203, DuPont will showcase its advanced offerings of Kalrez® perfluoroelastomer parts, specifically engineered for demanding sealing applications across a variety of industries, including chemical processing, oil and gas, life sciences, and pulp and paper. 

Valves of all types—control, pressure, ball, gate, butterfly, solenoid, and vacuum—require sealing components that withstand aggressive chemicals, high temperatures, and rigorous pressure cycles. DuPont™ Kalrez® parts, which include O-rings, valve stem assemblies, and precision-engineered packings, are meticulously designed to meet these challenges for leak-free operation and extended service life in applications where traditional materials may fail.

Among the featured products will be Kalrez® Custom Shapes (T-Seals, V-rings, X-rings, spring embedded seals, etc.) tailored for specialized sealing applications, and Kalrez® Valve Stem Packing (KVSP), designed to effectively reduce fugitive emissions, enhancing environmental compliance and operational efficiency.

“As operating conditions evolve, the demand for sealing solutions that balance durability, safety, and efficiency becomes increasingly critical,” said Brian Ammons, Kalrez® Global Business General Manager, Qnity™, DuPont Electronics. “Kalrez® parts represent a fusion of material innovation and application expertise, empowering valve manufacturers and end-users to achieve peak performance in the most demanding environments.” 

Tailored Compounds for Outstanding Performance

Kalrez® parts utilize proprietary formulations tailored to meet the specific demands of various industrial and electronics sectors. Through close collaboration with leading valve manufacturers, DuPont crafts customized solutions that align with stringent industry standards for reliability, safety, and efficiency. This tailored approach not only assists end-users in achieving compliance with regulatory requirements but also enhances equipment uptime and productivity.

Technical Sessions in Conference Program 
On June 5, Mohammed Boudrare, Technical Service & Application Development Engineer for Kalrez®, Qnity™, DuPont Electronics, will present two technical presentations in the Valve World Conference. Boudrare’s first seminar, Perfluoroelastomers Sealing in Rapid Gas Decompression, Supercritical CO2 and H2 Environments, is part of the Hydrogen session. His second talk, A Study of Various Elastomeric Materials Performance in Harsh Amines Used in Absorption Processes for Steam Methane Reforming & CO2 Capture, is part of the New Technology and Innovations session. Both programs complement the innovative Kalrez® solutions showcased at the Expo.
