DuPont™ Kalrez® Spectrum™ 7375 (KP7375) is a 75 Shore A black perfluoroelastomer (FFKM) engineered for high-temperature sealing applications that require broad chemical resistance combined with reliable water and steam compatibility. Built on a patented crosslinking system, this material delivers excellent compression set resistance and strong retention of physical properties at elevated temperatures, with a maximum recommended service temperature of 300°C (572°F). Kalrez® 7375 performs well in aggressive chemical processing environments where mixed media, hot water, and steam exposure occur simultaneously, helping maintain seal force and dimensional stability over long service intervals. Its balanced mechanical strength and low compression set make it suitable for both static and dynamic sealing locations subjected to thermal cycling.
Kalrez® Spectrum™ 7375 is commonly used in O-rings, gaskets, and custom sealing components for chemical processing equipment, valves, pumps, reactors, and steam-handling systems operating at high temperatures. It is often selected when standard broad-chemical FFKM grades lack sufficient steam resistance or compression set performance at elevated temperatures. This compound provides a reliable solution for processes that combine harsh chemistries with hot aqueous or steam environments. Canyon Components offers equivalent high-temperature FFKM materials designed to meet similar chemical, water, and steam resistance requirements as Kalrez® 7375 for demanding industrial sealing applications.
