Universal chemical-resistant packing for pumps, valves and reactors.
Pure PTFE packing is suitable for all media except molten alkali metals and free fluoride ions. It is used for sealing flanges, valves, reactors and pumps in non-contaminating industrial fields such as chemical and food processing.
With flexible adjustability, PTFE packing fits shafts and stuffing boxes well, offering outstanding corrosion resistance, good self-lubrication and excellent anti-sticking performance.
