STYLE 2070

Expanded PTFE Graphite Yarn with Aramid Core

Description and Application

Style 2070 packing is an interlock braid, utilizing TEADIT’s patented EGK yarn and a high temperature break-in lubricant. EGK yarn totally encapsulates a high strength aramid core in an expanded PTFE/graphite jacket. The aramid core contributes exceptional mechanical strength and dimensional stability, while the PTFE/graphite jacket provides chemical resistance, heat conductivity, self lubrication and a low coefficient of friction.

Style 2070 is a superior general service and corrosive service packing. Its high resistance to extrusion (four times higher than conventional PTFE/graphite packings) makes Style 2070 ideal for handling chemically aggressive fluids in high surface speed and high pressure applications.
