Description Graphitized PTFE Packing 1200 is manufactured through a specially engineered process. High purity micronized graphite is encapsulated in a PTFE (Teflon) matrix structure. The graphitized PTFE yarn (comparable to GFO® ) combines high thermal conductivity from graphite with all other great properties of PTFE. This combination gives the style 1200 packing great sealing properties that other products cannot offer: compressible, durable, self-lubricating, chemical resistant and heat dissipating.
