Gland Packing
Oil-containing Graphite PTFE Braided Packing
Braided from graphite-filled PTFE yarn and impregnated with dimethyl silicone oil. The graphite particles effectively improve creep resistance and high-temperature performance, reducing leakage paths and lubricant loss with less frictional heat; stable against strongly corrosive media, it is a low-wear packing that will not damage the shaft. Suitable for all media except fuming sulfuric acid, fuming nitric acid, aqua regia, fluorine and other strong oxidizers.
