The 3R 782 is made of an aramid core covered with graphite particles and completely coated with a PTFE jacket and has a high temperature break-in lubricant treatment. The aramid core gives it excellent mechanical strength and dimensional stability, while the PTFE/graphite jacket provides chemical resistance, heat conductivity and a low coefficient of friction.


This packing is suited for corrosive applications. Its high resistance to extrusion (four times higher than conventional PTFE/graphite packings) makes it ideal for handling chemically aggressive fluids in high surface speed and high pressure applications.
