A Proven Performer Spreads its Wings
DuPont™ Kalrez® perfluoroelastomer parts are engineered to stand up against jet fuel, engine lubrication oils, hydraulic fluids, rocket propellants and oxidizers, all in the presence of extreme temperatures. The exceptional performance of Kalrez® parts are proven in applications, including mechanical seals in the chemical process industry, aviation, marine and gas turbines, auxiliary power units, hydraulic actuators and bleed air valves and fittings. Kalrez® perfluoroelastomer parts are manufactured and are sold by DuPont and its authorized distributors.
Kalrez® AeroSeal™ 7777 and 7797, developed for outstanding thermal stability at 325°C (617°F) and excellent compression set resistance, have been selected for use in jet engines. Both have superior High Thermo-oxidative Stability (HTS).
The latest product Kalrez® 7800 resists corrosion with titanium, and is manufactured in accordance with AMS7257D.
