Darcova TEF-CORE XT Stuffing Box cone packing has a Fluoropolymer wear ring (TEF-CORE) molded into the specially compounded rubber cone. The TEF-CORE ring acts as a wiper and reduces polished rod friction. The specially compounded rubber provides high temperature performance (200° C), low temperature flexibility, and excellent resistance to chemicals, hydrocarbons, and abrasion.
DARCOVA TEF-CORE XT Stuffing Box cone packing is available with Kevlar for added strength and abrasion resistance, and brass for additional wiping capabilities.
