Gland Packing
Oil-containing PTFE Braided Packing
Braided from 100% modified PTFE yarn and impregnated with dimethyl silicone oil. With low friction, high lubricity and non-contamination, it is stable against strongly corrosive media such as acid, alkali and solvent, used for corrosive pump and valve sealing, especially where hygiene grades are required. Suitable for all media except fuming sulfuric acid, fuming nitric acid, aqua regia, fluorine and other strong oxidizers; the preferred packing for food, pharmaceutical and hygiene industries.
