Expanded graphite packing
The packing is braided from low-sulphur expanded graphite yarns, which are reinforced by cotton fiber or glass fiber. With very low friction, it does not damage shafts or stems. It also shows good thermal conductivity, chemical resistance and high elasticity.
Braided from high quality texturised Dupont aramid (Kevlar) yarns, which are uniformly impregnated with PTFE dispersion. The packing shows good chemical resistance, high elasticity and very low cold flow. It is wear resistant but may damage the shaft if not used properly. A minimum shaft hardness of *0HRC is therefore recommended. Compared with other kinds of packing, it can resist more severe media and higher pressure.
