JFY-4205 Graphite PTFE Packing

JFY-4205 Graphite PTFE Packing

This packing is braided by graphite-filled PTFE impregnated with a small amount of silicone oil. Graphite-filled particles can effectively improve the creep resistance and high temperature resistance of the packing, thus reducing the leakage path, reducing the loss of lubricant and generating less friction heat. It has good stability to highly corrosive mediums such as acid, alkali and solvent, which can be used for seals of pumps and valves with corrosive mediums. As well as, it is a low-wear packing without damaging the shaft.

Product Description

This packing is braided by graphite-filled PTFE impregnated with a small amount of silicone oil.
