DuPont™ Kalrez® 3065

DuPont™ Kalrez® 3065 is a highly-filled product containing carbon black and fiber reinforcement, designed to function without extrusion under extreme pressure. It has good all-round chemical resistance and excellent resistance to sour oil and amines. Kalrez® 3065 has an upper service temperature of 288 °C (550 °F).
The mechanical properties and chemical resistance of Kalrez® 3065 make it the best choice for many oil and gas well environments. In these applications, it is normally used in the form of V-rings and other custom parts rather than O-rings.
