DuPont™ Kalrez® Spectrum™ 6375 (KP6375) is a 75 Shore A black perfluoroelastomer (FFKM) engineered for broad chemical resistance and high-temperature sealing in the most aggressive process environments. Designed to handle mixed chemical streams, it delivers excellent resistance across acids, bases, solvents, and reactive media while maintaining reliable mechanical properties. Kalrez® 6375 supports a maximum continuous service temperature of 275°C (525°F), with strong compression set performance that helps preserve sealing force during high-temperature operation and thermal excursions. Its proprietary curing system enhances chemical stability across the full temperature range, making it a widely used general-purpose FFKM in harsh service conditions.
Kalrez® Spectrum™ 6375 is commonly used in O-rings, gaskets, and custom seals for chemical processing, semiconductor support systems, oil and gas equipment, and other industrial applications exposed to aggressive and changing chemistries. It is particularly valued in processes where low volume swell, thermal cycling resistance, and long service life are critical to equipment reliability. This compound is often selected as a baseline FFKM when broad compatibility is required and application-specific fluids may vary over time. Canyon Components offers equivalent FFKM materials designed to match the chemical resistance, temperature capability, and compression set performance of Kalrez® 6375 for demanding industrial sealing applications.
